 Okay, so let me, first of all, thank the organizers for putting together this wonderful conference that we are enjoying so much, and to all of you for being here after this wonderful dinner that we have just made. So then I'm going to talk about the, how are the electronic correlations in the normal state and as we are going to see what I mean with the normal state is the one in which we don't have broken signatures. So this is a work that has done in collaboration with Maria José Calderón and Anufridata from my own institute and with Alberto Comjalli from Universidad de Buenos Aires. So well, we have already quite a few talks on to his biography, so it's clearly that it does not need any introduction. So let me just remind you a couple of things. So well, we are going to focus on this rejuvening which we have almost flat bands in the moray. So here, as we have heard before, we have two ballets. So each of the bands is going to have both the spin and the ball in the generality. So we have in this flat band, so we have in total four flat bands and well, in the ballets there is, the ballets are related by terms of our salt symmetry. Some details of the flat bands depend on where there is relaxation or some aspects like the fermi-velocity that you use for graphene or something like that, but well, there are more examples, essentially that. And you know, so well, after this, Pablo had experiments and many other groups. So people have been able to dope the system in each of the bands. So in this flat band, we can dope up to four electrons per moray unit salt. And then if we dope with four electrons, we expect to have a band insulator that it has been observed. If we dope with four holes, it's expected to be. So we expect to have a band insulator that it has been observed. And of course, the surprise came when correlated electrons were observed at other interior fillings of the flat bands. OK. And well, since then, there has been this huge plethora of correlated states that have been observed in this system. And these correlated states include both states in which the symmetry is broken and also, let's say, non-conventional behaviors in which that happened even or believe without symmetry breaking, like, for example, this unknown familiar behavior of the resistive. So there has been one question from the very beginning in the field, which is to which is then mod physics is important here. So let me, first of all, remind you what we mean by mod physics. Not all the correlated insulators are mod insulators. So when we talk about mod insulators, we are referring to the localization of the electron. So it's a view in real space as opposed to k-space. So one thing associated to mod insulator is that really having the insulating state does not require to have symmetry breaking. So if we have mod insulator, we should expect to have it. If it's a real mod insulator, we should expect to have it even without symmetry breaking. And, well, if it's a mod have a like mod insulator, we expect that at integer family. Another of the characteristics of the mod physics, in fact, so the physics that are associated to, let's say, local physics, the one that is coming in the atom, even if it's an official atom, is that it's not only the insulator, what is anomalous, but also when we approach the insulator either through doping or through increasing you, we also have a strong anomalous, strong changes in the meta. So you can see here the type of technique that has been very useful over the past 25 years to study this type of changes is that has been done in the dynamical mean field theory, and you can see the dynamical mean field theory picture from this. So this is, well, a single orbital habit model, in particular, for a better lab is that what you can see is that imagine that this is a non-interacting density of space, and this is the quasi-particle band. So this is our well-defined band, and we are starting increasing you. So if we increase a lot, we have an insulator, mod insulator. And then we have this habit band. So I think we are all familiar with the habit band. And then what I want to focus is that when we are going to increase in you from the non-interacting density of space to the mod insulator, so this quasi-particle, so we are sending a spectral weight from this quasi-particle band to the habit band. So even if this space at intermediate you are metallic, so the spectral weight has nothing to do with the, or it's a strongly changed with respect to the non-interacting one. Also, if we start developing the insulator, and then we are not anymore at the integer filling, it's not that we just destroy completely all the effects of the correlations, but what we have is that so we start having the habit band, and then we start adding the doping to one of the habit bands, and there is a change in the shape of this habit band. Okay, and then for a range of doping, the effect of correlations is still quite evident in the spectral weight. This type of physics has been looked at as people have been, has studied that over the years in well-known, well, strongly correlated electron systems, like the cooperates, like the iron superconductors, or like heavy thermals. In each of these systems, also each of these systems share some properties in the sense that they all of them have very complex phase diagrams and also with many other phases, they have all spectral weight organization, but the way in which these local correlations show up in these systems, it's different. So somehow, like they say the cooperates, we normally describe them as single orbital Haber models. In the NIC type, they are multi-orbital systems, but also whose coupling is playing a very important role. So they are what we call hood metals. In the heavy fermion, the physics is the physics of having both local electrons and it's in an electron. So the question is what, so whether do we expect this type of mod, like physics, or the effect of the local correlations into this bilayer graphene and in which way they show up. So then what I'm going to do and in order to try to separate the behavior of this spectral weight organization that we can think that it should appear if local correlations are important from the effects that produced by the symmetry break is what I'm going to do is I'm going to focus in the normal state. Now, in the case of twist bilayer graphene, you know that we have 11,000 atoms per unit cell. So then there are different ways to study the systems. In principle, so there's some people who start in a fully atomistic viewing with including all these atoms per unit cell. Then there is people working in with the interactions in K space in the continuum model that we have also heard some talks in these conferences, but if we want to see the effect of the local correlations in this twist bilayer graphene, it will be convenient to have, let's say, effective atoms, effective atoms, which means all effective orbitals, which are associated to all the moiré neurons. So somehow to treat, so to have effective orbitals for all the unit cell. And this is what it can give us the descriptions in terms of moiré functions. So again, as this has been also discussed during this week, this how we can do or whether we can do a barrier function model, it has been extremely controversial. It's still controversial in twist bilayer graphene. So the issue here is if we want to describe the system in a barrier function model. So the question is how many bands do have to include moiré in the system, whether we can have just these two bands or we have to include moiré, which is the center of effective orbitals. If you see here, there are different lattices in our moiré. So we have the triangular lattice that is formed by the center of the moiré unit cell. There is a honeycomb lattice that we have here at the border of the moiré unit cell. There is also a cabamell lattice that it is formed here in between these two VA and AB points. So I'm not going to go into details, but so the model that I'm going to use is this modeling with there are eight orbitals per or eight barrier functions per valley that it was proposed by the group of carbons. So here the spatial symmetry are satisfied in each valley and also some of the remote bands are included. So you can see here this model contains effective orbitals in the three lattices that I have mentioned that there are. So in particular there are orbitals in the AA region, which is here this triangular lattice that you can see here at the center of the unit cell. There are AB orbitals at this honeycomb lattice and then there are also orbitals at the cabamell lattice here in purple. Also the symmetries of the orbitals each of them. So what I want you to focus is that well we have a lot of orbitals in each valley, but there are some orbitals that are clear that they are playing a special role. In particular you see here this here AAP plus orbital. You see that they are the ones that are giving most of the character of the spectral weight at the flat bands. They give these at the flat bands everywhere except at gamma that they go to the remote time. Okay. And so here at gamma you see that the other orbitals have some weight. A couple of years ago we calculated the interactions for this system. And of course you can imagine that having so many orbitals we have a lot of interactions. Because we have both the interactions that are in the so intra-orbital interactions and the interactions which are between all the orbitals. So in this calculation we look at the gate as far so that means that we are not screening the long range part of the long interaction. And in fact well when we look at the interactions and if particularly we look at the density-density interactions so we see these are the let's say intra-orbital and intra-unit cell interactions that we will say for our effective orbitals the outside that the gate always remember that we have these are here and these other ones so they decay like the potential that so that the interaction potential between the carbon atoms. Okay. So there are also exchange and whose coupled interaction they are much smaller and in what regards the multi-six I'm going to throw them away. It could be important for some symmetry breakings but I think they are not playing a role for the calculation that we are doing. Okay. Now already this system if so this interaction this model if we do the calculation at the heart rate level this is already giving an effect is the formation of the bump. Okay. So this is an effect that it was early proposed on the base of atomistic and continuum models by Paula Mejado and by Paco Guinean and Nils Valet and here so this model also gives this type of effect so this means that so if we start this survey this is the endowed system here I'm focusing on what I'm going to do all the time in the talk is I'm going to focus here on the low energy part in the picture so if the system is it's not dope this are advanced if we dope the system already at the heart rate level that is the formation of the bump so at gamma the doping with holes this person at gamma is that higher energy as compared to the end of system if we dope with electrons that's the opposite. You hear also a bit about this in Paco stock but we would like to do something if we want to describe the effect of local correlation we should go beyond the heart rate. Now of course with so many interactions it's we cannot go with dynamical mean field theory to assist them in which we have all these interactions also in particular because if it is single side dynamical mean field theory it's we cannot even treat the long range part of the interaction. Now the question is that if we now look to the system so not all the orbiters are playing the same role as I have said at the beginning so we have I have first called your attention to this orbital okay so on one side these are the ones that are the most important ones because these are the ones that are the flatten but also is that when we look at the interactions so these are the ones that they have the largest interaction so with if I assume this screening constant is going to be of the order of 40 milliolectron volts as compared to the other orbiters we have a smaller interaction okay so here the value of the screening constant we chose it on the basis of a comparison with atomistic calculation it's of course not well known in the in reality so the community that it's not there are many values I think it's going to be probably between 10 and 20 but of course so the interactions just scale at 1 over epsilon. Now what this is going to be important is of course how large is the interaction as compared to the bandwidth and you can see here this what we look at a couple of years ago is like so this interaction for this orbital so these are the orbital resolved density of state so this interaction is larger than the bandwidth so it's in this case when we do expect that this local interaction is going to have a strong effect while this other interaction the one in the other orbiters are going to be smaller than their bandwidth so what this is telling us is that we expect that these two orbitals so in total we have four we do expect that they will suffer from this strong correlation from the effect of the local correlations and that mode physics can be important for them while for the other one so we don't expect mode physics to play an important role so then we can separate the orbital between these two groups and so then what this take us is to a kind of effective model which is heavy for me or like in which we have so somehow it's going to say so four orbitals super valley which are this one very strongly correlated and other 12 it didn't unlike all even if these orbitals are it didn't unlike this does not mean you if you have seen before the interactions you can see that these interactions are large so I don't expect them to give mod correlations both real spectral weight organization but I cannot throw them away so then what we are going to do is we are going to do a combined approach in which we are going to treat the interaction that we expect to be the one relevant for for mode physics which is the one in between the AAP orbital so the strongly correlated orbital and these are going to be inter orbital interactions so I'm going to treat them with dynamical mean field theory while I'm going to treat the other interactions all this other one okay so in this way we will for example reproduce the well the band the formation that it will not be correct if we throw these interactions okay so then so well I'm going to do the calculates the calculations that I'm going to present having done at 1.2 Kelvin with a continuous time once in Monte Carlo version of the dmht and this value of the spring and what I'm going to do is I'm going to focus on the normal state as I said in which we are going to impose that we don't have symmetry breaking this is something that one can do with a technique this is clearly this is a really ongoing work I will tell you a couple of ideas in which way it's ongoing but it's ongoing both in the way in which we are doing the procedure but also in the type of analysis that we have done you have since it's still very preliminary analysis but I think that it's even so I think it's worth it to start talking about that so the idea of the procedure is for this dynamical mean field theory plus heart rate is that well we first include all the interactions at the heart rate level to start from a reasonable but including this this interaction that later we will see that the dynamical mean field theory so the first step we are introducing all of them and we subtract the heart rate double counting so there are there are several prescriptions for this double counting and they well they have some effect on the so far of the let's say details but it's something that we are also looking at then with this I go to once I have done some consistency here we go to the dynamical mean field theory for this orbital so then on one way we subtract the heart rate interaction that we have included before on the other one is this orbital itself are going to be entering an effective way then we go so then this is going to change the density we should go back to the heart rate and so on until everything converges so today I'm going to present results here so then let's say this is a single shot heart rate plus the MFT so in the same way we have a self-consistency here self-consistency here but still these results are not at the full self-consistency I expect that the main picture that I'm going to give you it's not going to change but some details could do okay now these are the angles for which I'm going to present results so when the model was proposed with the taxi that group proposed this model they were considering a relaxed twist so what we have done in order to better compare with other people's work is we have adapted the model to the B-Street and McDonnell continuum model and so well we are these are the two angles that I'm going to discuss this one you see it's a bit wider and this is closer to the magic angle okay you can see this here in black is the B-Street and McDonnell model and in red we have a variation that we have one thing that I didn't mention before this is not a body model in the sense that it's going to really gap but here so this approximation somehow deviates okay okay so let me start with a 1.20 angle to warm up so what I'm going to do is in order to discuss the effect of the local correlations I'm going to be comparing the results that you obtained with what you obtained with DMFT plus heart rate okay so this is a case in which the system is done with holes and you see here that if we now go from the so we have this deformation that I have mentioned before this is each of the bandit will be at half feeling from the charming side point as I have said before we can do four electrons or four holes so if you look this is the dynamical mean field theory plus heart rate calculation and there are several things that can call our attitude well the first thing is that we more or less still have this shape of the band okay they have three shape of the band but somehow this band is like very badly defined okay so what you can see is that it's very blurry so what is happening here is that there is a transfer of a spectral weight from this band which is completely quasi particle light it's completely coherent to many body states which are incoherent these are two Habermann which are always incoherent parts so you can and so this is what you see here this is Habermann light and then you can see that also the dispersion here so at this angle we have it still our quasi particle band here but so you see that it has become a bit narrow okay this is the comparison that in many correlated systems when the band with renormalized and becomes smaller so this is the equivalent another two things that we observe is that okay so here before I had said that at gamma so we didn't have the correlated orbital the orbitals at gamma where they non-correlated one but you see that this this is also to some extent affected so well in reality what is happening here is that these other orbitals are affected through the scattering with the non-correlated orbitals okay so then that's that's because they are affected and another thing is that this is the remote band you see that also the remote band that we didn't know in the beginning in the field whether they have to be included you see that the remote bands are also somehow touched of course this is going to depend on how large is interaction so if we now these were still with the same with the same angle if we now changed the feeling so what do you see is more like the same thing the main difference is that so with the how is the underlying particle band is well that this incoherent spectral way so it's for hold open is mostly at positive energies at the time to try to point and up is is more like half and half and when we dope with electrons it goes to negative energy so this is kind of behavior that one aspect generally from about six okay now if you we look even if it looks quite let's say evidence here in the band when we look really at the density of a state and we compare that with a country but we see is well so somehow we really clearly this this we have said how this spectral way and you can see also here clearly at the band so this is the this has changed but let's say is is not absolute it's not too dramatic okay it's there and it's maybe can be detected but it's really not that huge okay so with that let's now go to the one point zero eight okay I'm going to see here it's much more okay so here this is only have three so this is the band we have here be the and dope and dope bands you can see that even if there is here at this heart rate level even if at the heart rate level even if there is some changes in the density of a state with dope in there is still quite as small at the heart rate level now if we now go to the DMFT plus heart three this effect is huge and it's very large both if we compare the results DMFT plus heart rate we compare with heart rate you can see here how different is the density of a state this one look at this energy scale that I have here but also if we if we dope the system we see that the density of a state is very strongly dependent on on doping okay now if we and you can see also this is a non-integer feeling before I was an integer feeling if you see a non-integer feeling you see also that there is a very strong effect of the correlations at this value so it's different than the one that there is at the integer value but still it's very large you can see how is the let's say charge versus chemical potential care and you can see again in heart three this is more like a line except some small thing that you have at the point so while comparing we have when we look at the charge versus the chemical potential in DMFT plus heart rate we have these clear so what this is telling us when we have these steps and I want to emphasize I do not have any symmetry breaking is that we may have an insulator so we look more carefully is here at n equal minus one here and doping with holes okay so I'm only in the hold up region you see here that we have to reach it up in the system okay this is a model so like and you can see later I will go to the shape of the now in the case even if we have this set here at n equal zero and with two holes so if we look carefully at the density of effect here this is not exactly zero but what is happening you can see here if we see here the system well it's it's a very small state there so it's something like it's close to be an insulator so somehow probably if we increase it lightly the value of you it will be an insulator now what is happening here so this is around 45 this is the one that it comes here from this this electric constant is 44 the local you around 44 45 something like that so if you go to this charming point then what you see is different so somehow here it is almost as it is like it's going to disappear as if we increase slightly you but here it is different so we have this clear crossing this does not seem to be disappear and in fact this is a state that we have here these are this is a spectral way that is coming from the non-correlated so okay so this is not so all this spectral way that is incoherent if it belongs to the correlated orbital but this this spectral way here is it belongs to the non-correlated orbital and I don't think that if I increase you it's going to go away so you can see here how it's how depends the density of states on the pin so what you can see is that if we are at the charming point so these are the however but somehow it looks like that I kind of to pick a structure here now if we are at minus one so it's like if one of the peak is and but if we don't the system is as if the other peak is the one that shows up you see the differences in energy we continue doping and so well we see clearly both in the dope cases we see clearly this quasi-particle peaks telling us that the system is metallic but the peak more or less follows here at this energy then we go back to the interior and now it's n equal minus two and again this is the one that shows that we don't regain and then we have this peak here so this is not just a simple Haberband somehow we are still cannot say exactly where this is coming from but you can see here where this how this looks like in the band so here at the interior feeling we have this kind of it's a very strong feature in the band okay then when we go to to the interior these have become quite incoherent so this is far from the chemical potential so then and these have happened already at the very small doping then is that we continue doping so somehow this is still very very blurry so different from here and then we go to the insulator and it's again so it's a very very strong feature and so this one is much smaller I have put here I don't see if you want us to see that some line to see how this peak is not just that we send here we send a spectral weight from the quasi particle here is that really the weight that there was here has somehow gone to a bit lower energy and this is well without even beyond two and again this blurry spectrum shows so another thing is that so normally when when you do you just work with a simple have a model of the single orbital and you go to and you try to see how they have our bands appear so what you see is that so these have advanced are separated this is the single orbital model this is what I showed you before this is a approximately okay the idea is that this is approximately that they are the distance you and that this way is more or less of the order of the bandwidth so here we are getting it's also somehow different in the sense this is for the same band structure and this is all so all of them correspond to the same is great same angle but we are just changing the interaction and what you see is that this the width of the have advanced is increases with the interaction so somehow it's clearly not determined not not essentially given by the bandwidth it's something different so it's a bit different to what we are used to and another thing is that we can that we can ask ourselves how is the relation between so how does the relation between the flat and the remote path change something that we can ask and in fact it was one of the first question I was asking myself when we started to do this is whether this gap will close when if we manage to go to an insulate and the reason I was asking this myself is that if you do you try to describe this type of system with a simpler technique for mode for mode like a leather skin something that you so this gap is associated to the hybridization between the correlated and the non-correlated sources okay so somehow when you go to mode in this is what I say in for example in the slave is in description you expect that this gap will close because this hybridization will manage so and then the question is what so this is a more careful technique so what is what we expect here well I have shown you before that really we can really go to an insulator and this gap really has not closed so somehow one can see that it's something like it's suppressed so if if the gap it will be suppressed we will have expected to have a spectrum like this so somehow there is a pressure of the gap but it does not closes completely and in particular it does not closes for the insulator now another thing that we observe is that we are sending a spectral way as I said before we are sending a spectral weight in an incoherent way to positive and negative energy but in particular here what you can see is that we have sent some incoherent spectral weight to negative energies and so this makes that the remote ones are going up eventually and that this will of course depend on the details on the interaction anything eventually what we find is that really this remote band can close the chemical potential so somehow they could even contribute to the permeable level ok so this is what I wanted to say so the main answer is most physics do matter to this biographies so we do have to take most physics into account I personally think it's going to be behind many of the experiments that have appeared so far that this is something to look at carefully this is the calculation that we have done is based on this dynamical myth theory plus heart rate approach that gives light to a kind of well based on a kind of complex heavy thermo life model we have a very strong and not independent reorganization of the density of a state and of the spectral weight but this organization it's a bit nontrivial we still are not understanding all the details the correlated orbitals are the ones that are going to be of course more affected but there is also some effect for the correlated orbitals the gap to the remote ones is suppressed but not close and we can have it in charge transfer something important is because it is all this organization of the spectral weight any calculation that look at the symmetry breaking so it should have in mind that even if they are doing a kind of band instabilities picture so these bands can be very very much different to the ones in the underlying model in the non-interactive model and of course well to look for final details one really it will depend on value of interaction details of the band structure and some of the details that I say like once we have the full self consistency and so on okay so thank you thank you Lenny questions thank you is there any data what is the definition of state near integer feelings or the compressibility chemical potential versus density and the compressibility there are steps so the compressibility should diverge probably what are the indices and things like that so when you say that there are experimental or whether we have that we are still not comparing with the experiment so somehow is that there are these I don't know if this was now the question is that different people is interpreting that in different ways so this is what one have to show this let's say for example this cascade of phase transitions so somehow it's showing that there are these jumps now the question is still it's to be seeing what is exactly the origin but yeah I think this this changes can be very much related I think this was compressibility I guess my question was about the universality class of this transition indices corresponding to the compressibility are known that will determine okay that we have noticed so I think this is compressibility yeah two questions one about your theory another about experiment just before you do dmft well you don't know how to you showed the bands for a different end and correct me if I'm wrong but each time on vertical axis was energy minus chemical potential which I assume was adjusted by yeah well we are just putting it there yeah if you amplify this band picture where is the zero energy state in this band it was pretty flat no no when you showed already pictures with hard tree but without dmft for different end and equal to zero and then this is hard tree without the energy simple question it looks from at least from what I see on a bit your zero energy shifted by zero means epsilon minus it's always at K and K prime points am I wrong with this okay so probably it looks like it's so somehow it's probably here we see better what you want to say this one it's not so let's say it's not exactly for example here so you see here the K and K prime is slightly let's say so it does not it's not necessarily exactly at K and K prime but it's only that probably we should zoom in to see it better yeah I was thinking about it without your shift spectral weight from this band into sub bands whether you have you see evolution of the distortion of the Fermi surfaces with N we haven't we haven't looked at Fermi surfaces yet so you say like do zero energy and look we haven't done that yet yeah okay I think that may change because for example you see so in principle in other calculations that I have done the Fermi surface changes and you can see I'm sorry with DMFT but maybe second question is quickly about experiment when Ali presented his data he showed peaks pretty sharp peaks which cross Fermi level and go on the other side if you change topic in your picture when you also show the data for the density of states is there any correspondence with what he see we are still so we first want to understand well our density of states so and and to see well interactions and all that particularly over all understand this spectrum before trying to compare so far we see this very strong organization and it's that so somehow this chart versus new steps looks very promising but I'm still not comparing to experimental data so I'm still looking at the I think that there is going to be clearly correspondence at least to some level in the sense for example if in our case the bands are completely dope or completely empty so I do not expect to have this strong organization that we have here but it's going to say this is still very early results and we are still are not there so yes from the voice from beyond okay very nice talk Ellie I have another question for you wasn't clear to me first of all do you have the full SU for you know model yes sorry well it's sorry it's yeah it's it's 34 yeah you do okay I have value and it's 503 so all of your bands have this full full degeneracy how does your model contrast that of song and brand of it is it the same model I knew this this question was going up yeah so the model is not exactly the same in the sense that so what he has but I think I think they are going to give the same physics so let's say so no okay so what he has well the orbitals the correlated orbitals are the same okay in the in the two or are completely equivalent in the two models what is different is the internet or in the internet part so he puts four bands which are in K space he's not doing a bunny or model like and he has a kind of with the linear coupling there and so I think that we are in fact looking at that I was discussing with him recently but so I'm looking to see what I think is that if we expand our six internet orbitals close gamma and do proper change of basis I think it's going to be I will be able to recover to within some accuracy his model so I think the physics should have been the same okay very good and in your CT in your in your continuous time Monte Carlo are you getting below the con the temperature or the effective coherence temperature or are you forcing into it where how is that working so what we can do is what we get in the calculation is the cell pharyngea frequency dependent cell pharyngea and we do it at the fixed temperature and so far we have worked with that temperature somehow what you see is that if you but we have not done that yet but also because so we are still okay the question is if I increase the temperature so at some point if I lose if I have a water particle and I squeeze the temperature eventually I will lose the particle so somehow I think probably that is the equivalent but we haven't thought of that yet okay thank you very much so if I understood correctly you are getting an insulating state at only n equals to minus one but not at least cnp minus two or even at minus three how are you justifying that fact and secondly how much is the band gap at minus one how much is the band gap at minus one okay so well the first thing is I'm getting that at minus one I think that whether at this point whether I get it at minus one or minus two probably that can depend slightly on details on the band that we use well I don't think I'm going to get it when we go beyond it has the charge neutrality point because as I said so no I'm going around that okay so let's say here so I get the steps in all of them so somehow is that the correlated orbitals they are very much in mode the correlated ones but here at the charge neutrality point the non-correlated orbitals really go there to the chemical potential so I don't think again we haven't looked at that yet carefully but I don't think I'm going to disappear I think this is going to be there even if I increase the interaction this one is I think it's almost about to be mod but it's going to say if you change it slightly you are underlined bands and you have maybe the manhole but this slightly different doping maybe I get the insulator at n equal minus two and not equal n equal minus one that I still think it's a matter of details so I think there is a difference with respect to the charge neutrality point and the other integers and I think that the gap we are getting but I think this is going to disappear so I don't know let's see I think I have so how is this very weakest state some that we obtain for example here some of the final structure that I get close to the chemical potential could change once I have the full self-consistency so that is what is happening for example I think that's already very detailed discussion okay now what I was going to say some of these in the full self-consistency is disappearing not of course that okay so let's say me once again and we will meet at 11.10
