 We're trying not to impose things for people. Yeah, for the way, two restaurants are very easy to jump on the bus and maybe go to Barcala. For those who don't know where the restaurant is, it's immediately after Barcala. So you leave the bus on Barcala, move a little bit towards town and this is the first building on the right, if you move towards town. So this is really... Rammer. Yes, but not everyone knows that we went there after that. Okay, the practical thing is how to get back after the restaurant. And for this, there is a principle that even later the bus goes to airport and stops in Barcala and then stops in close to ICTP, but other options are either walking, if there will be no rain or basically make a group of foreign buyers and then ask for taxi, that's the national ability. So, but hopefully there will be no rain when we go back. Yeah, I think that midnight the sea bath actually goes all the way to Guinea, so the other side. We, maybe it's it, but it's not on a schedule. Yeah, it's not on a schedule. I mean, we can't go on the six o'clock midnight from the central station to Barcala. Only was, maybe it was... Yeah, it was a part of the midnight from central station to Barcala to Guinea. Okay, guys, it's... There are many options. There are many options. Yeah, so, yeah. Yeah, let's do it. Okay. Hello, everyone. We're starting our poster presentation session. My request to poster presenters to be precise on time and we spend one minute discussing your poster. And that should be enough to be able to convey the message. So I'm going to invite speakers according to the list. Please be prepared to share your screen right away. So we are starting with Mahdi Mashkuri. Please share your screen. Hello. Can you hear me? Yes. Good. So I share the screen. I hope you can see... Great. Let's go ahead. Okay. Thank you. So I'm Mahdi and I want to show you this work. So this is basically based on a proposal from Jean Kane and Mellor where they considered a hip structure of an iron-based superconductor and a strongly spin-orbit couple drushpa layer, which has, like, in the case of an iron-based superconductor. So this is basically based on a proposal from Jean Kane and Mellor where they considered an iron-based superconductor and a strongly spin-orbit couple drushpa layer, which has, like, interestingly three different phases. Red is the topological and the blue is the trivial, which is separated by this nodal phase. And our message is that when we evaluate the density of the state, we see, if you start at the red curve, which is a representative topological point, we see that the red curve becomes gapless while the trivial phase in blue is robust. And the green is for conventional space superconductor. We also looked at the phase diagram and we see that generally the phase diagram has the expansion of the gapless phase, mostly at the expense of topological phase. In contrast, the blue region, which is the trivial phase, is quite robust. I think we can explain this by looking at the disorder in single impurity and dimers, which we looked previously in this PRB. I would be very happy if there was any questions or comments to be reached by this email. Thank you. Thank you. Thanks. Thank you very much. Next speaker, Rashid Massour. Rashid Massour. Rashid, can you hear us? You started screen sharing, but we don't see anything. We don't see anything on the screen. Okay, since we're having technical difficulties, maybe we can switch to the next person, and then come back to Rashid if the issue is resolved. Roman Mukachev, please go ahead and share your screen. Is it okay? Yes. Yes, please. Good afternoon, dear colleagues. My name is Roman Mukachev, and I want to introduce you to our work on the study of magnetic properties of an metallic compound. We have already performed several calculations with the compounds of this type. Would you like to share your screen? I think I'm sharing. Maybe I will try another one. Is it better? I don't see your screen. That's strange. You can click on share screen button. I'm sharing it right now. We just see your logo. Okay, maybe. This was just a video. I have some software problems. Okay, yeah, maybe you can discuss it in words without sharing your screen. Maybe that's better. Nothing? No, we still cannot see your screen. Sorry, I don't know. I really don't know what's the problem. Okay, look, unfortunately we are on a tough schedule, so maybe you can say just a few words about, and then those will be in the queue. Yep. In this work, we are studying manganese and ruthenium compounds, intermetallic compounds with manganese and ruthenium, and the compound with ruthenium showed different values of the density of electronic states at the Fermi level from the previous study compounds. So ruthenium ions remains practically non-magnetic. And as a show of my poster, that's like changing densities of electronic states and other properties. And doping with ruthenium ion leads to changes also the lattice parameter electronic structure and properties of compounds. That makes this system interesting for further study. So maybe I can post my poster in the chat or somewhere else. Yes, please. Thank you very much, Roman. Next speaker, Shantanu Mukherjee. Please unmute yourself, Shantanu. Can you hear me? Yes. I can hear you. Time is running. Yeah, so please. Yeah, so I am Shantanu Mukherjee. And the title of my presentation is electronic vortex interaction and fermion pairing. So in this work, we have chosen a Boson-Fermian mixture model which closely resembles the model proposed by Friedberg and Lee in 1989 as a model for high-tech superconductors. So this is the model by Friedberg and Lee. And we consider here bortices in the scalar matter. And as we know that bortices construct magnetic field in the airport and also fermions have access source of magnetic field. Therefore, in such a model, an interaction between electrons and bortices is inevitable. So in our work, what we want to do is to derive an exact form of this interaction and dualization may lead to an answer. So following the Friedberg model, we take an relativistic model like this where we have neglected the direct coupling between bosons and fermions and dualize this model. And therefore, we get this dual model where the two-form gauge field couples both to this fermionic current and also the wall sheet of the dual string which represents bortices. Therefore, bortices and this electrons are interacting among each other by exchange of the two-form gauge field. And this is the electron-bottice interaction we wanted to find out. And one can show that this electron-bottice interaction can give rise to electron-bottice attachment. And this is represented by these two equations. So if we take two electrons and immerse them in a background superconducting medium, then two flux tubes can be connected to these two electrons. And therefore, they will be connected to each other and form a stable pair. So therefore, we see that electron-bottice interaction emerges out of dualizing a boson fermion mixture model and for nearly static electrons, bortices attach to electrons and lead to formation of pairs. And also, we have recently shown that these bortices attach particles over fractional statistics when the system is reduced to a 2 plus 1 dimensional manifold. So, thank you. And one, if someone is interested, one can contact me in this email ID. Thank you. Thank you. Next speaker. Fahim Sayed, Fahim Naqvi. Fahim Sayed Naqvi. Go ahead, please. Not here. Not here. Yeah, next one. Next one. Moved by Rahman. Yes. Hello. Yes, we can hear you. Please share your screen. Please go ahead. Moved by Rahman. Please speak up. We can hardly hear you. Calculate the lexation using the Kaldis formulation. There are many critical methods apart from simulation. Green function cubometer and Boltzmann transport hydrodynamics. And to explain the electron transport property of this sort of material. The simplest one of the Boltzmann transport hydrodynamics, which treat the scattering of leptons within thermogolded roots, but they're suitable only for the pure system in thermo little bit. And for scattering from the limited for other types of disordered material as well established feature in the most simple is that the disordered scattering causes quantum interference amongst themselves for passing power. A complication arises in the calculation of transport properties. Due to the modification coming out the quantum connection disordered system. The critical method that is well suitable for incorporate this interference effect through the Kaldis formula, which is based on the non-equilibrium green function method that we use. And from this we calculate the first collision integral and put this value in equation one. And from this question two, we obtain equation three from equation three from some approximation we obtain in disordered limit. Relaxation rate is a linear dependent on temperature. And for the pure limit is often the square part of the system and using this relaxation rate. We obtain that is from this. Your approaching. Yeah. And this is my numerical and integral from which we can clearly see. When we in increasing the disorder, the system, the resistivity is enhanced. And this, this is our calculation. And for the query we can contact with this email. Okay, thank you very much. Thank you. Thank you. Everyone hear me from those who are going to give up for that. You have one minute to make a presentation. Don't try to give introduction. One minute. About those ideas that other people should be able to contact you if they're interested. So try to make a point point from the beginning. Okay, next speaker Francis Miriam Orlich. Hello. Just give me a second to share my screen. Can you see that all right. Yes. Okay. Okay. So hi, I'm Miriam, and I'm going to be telling you about the Kagome lead bladders, which is a Kagome lettuce, but with an extra site added at the midpoint of each font in the same way the lead bladders is constructed from the square lettuce. It's a model organic frameworks, and it's a simple model of the recently discovered level organic superconductors. We found using a tight binding model that this model has five flat bands. And our aim was to understand why the present and to see whether these bands would survive in a real material that breaks the assumptions of this simple model. So the flat bands arise from the apology of the lettuce through the construction of localized Eigen states which have the energy of the flat bands. And it slips due to destructive interference. Now this picture still holds even after adding the metallic onsite energy and the metal metal hopping shown in figure one. However, when the ligand hopings added you can't make this argument anymore, and the new Lucy's at flatness at the bands. However, when this happens, our bands at half fillings are still flutter and more isolated than those are twisted by layer graphing for a vast array of hopping strengths. Now you can see this in figure four where I've plotted the band gaps on either side of the central bands, normally seven bandwidths. And as you can see the band gap bandwidth ratio for the Kagome lead type binding model is lighter than that of twisted by layer graphing for a similar model for a significantly broader range of hopings than is likely to be seen in a real material. So because of this the Kagome lead bladders is likely to display funds strongly correlated behavior such superconductivity, leading us to a whole new family of unexplored materials. Thank you very much. Thank you. Thank you very much. Thank you. Next speaker. Omid Reza, a ranch bar 90. Omid Reza, a ranch bar 90. Next speaker. Divya, a robot. Divya robot. Not here. Next speaker, Jose Rodriguez. Great. Can you hear me? Yes. Yeah, thanks. Organizers and chair for the opportunity. My name is Jose Rodriguez. I'm from Cal State LA. So I'm going to talk about some theoretic work, trying to understand compound we've all been trying to understand iron cell and I electron dope which is a high temperature to bring up there up to 50 degrees Kelvin. And so I looked at another. Some of my colleagues looked at nesting and instability story in order this is not the Fermi surface of iron cell and I but you can get something that approaches it by looking at adding fluctuations hidden spin fluctuations. And these are the fluctuation fluctuations I was looking at between orbitals in particular the isotropic orbital so there's no pneumaticity in this, in this model. And then if you do. Again, for Glendale theory, sorry, Eliasher theory with fluctuations of the two bands are connected with these orbitals. And if you look at the, the fluctuations at criticality so this is a critical spin fluctuations near one at a critical near one critical point you can get a list of transition where the, you get electron pockets, you get. Let me try to get this figure here. Ladies and gentlemen, you get electron pockets on these orange circles and you get a whole pocket at the corner of the wrongs on you get a whole pockets at the other corner. The interesting port is the way function real normalization of the whole whole pockets is weak it's very faint whole bands, whereas the electron pockets are moderate so it potentially can describe electron so on this list of its transition. And you, you find I found a Cooper instability on as plus minus pairing where the sign of the order parameter Cooper pair alternates between the hole in the electron bands. So if you're interested in anything the details, or just really understanding this here's the paper that was published last year and I'm, I'll put my email on the chat if you want to talk with me chat with me thanks. Thanks. Thank you. Next speaker. Let me stop here. Thank you. Next speaker. Can you hear me well. Yes, please. I wanted to talk about the fine structure of excitons in type two team the heterostructures today, where we describe the electronic and optical properties of molybdenum dissonant tungsten dissonant type two heterostructure using first ab initio methods and then tight binding with a solution both coupled with solution of metastalpeter equation, which adds to exit and expect to. So we start with determining the electronic structure of molybdenum dissonant tungsten dissonant from first principles. We obtain the type to bond alignment and conduction band minima in Q point as you can see here. Next, we perform the analysis of concham wave functions allowing to detect the leading layer and spin contributions and construct a minimum type binding model of this heterostructure which allows us to understand the orbital contributions to block state and study the effect of wave functions on the exciton expect from so all the topological properties of the system. Finally, we accurately solve the betasalpeter equation and determine the exciton expect from for that, as you can see on the last plot. So we define both intra and interlayer excitons, and we use simplified Ritova K additional local screening theory here. This all will allow us to finally study the effect of more a potential and comparative fully tight binding approach to excitons in twisted more heterostructures. Thank you very much. Thank you Katarzyna. Thank you, Dr. Eker. Yes, you're solving. Can you hear me. Yes, we can. Great. Let me just pull up the poster. Can you guys see the poster. Yes, we now can see your poster. Yes. Great. So I'm going to talk a little bit about artificial graphene quantum dots. Specifically, this triangular zigzag edge triangular graphene structure. What's special about this structure is there's a sub lattice imbalance between sub lattice a and B. And this leads to broken symmetry and gives spin polarized ground state. So I developed some model to describe the system in terms of artificial potentials at sites denoted by the points on this triangular lattice will hexagonal lattice shape as a triangle with zigzag edges. And what's special about this system is that if you diagonalize a single particle Hamiltonian, you find a nearly degenerate shell at zero energy or at the Fermi level we'll say. It's not perfectly degenerate due to next year's neighbor hopping terms that emerge in my Hamiltonian. So then what we can do is understand many body physics on this shell degenerate states as a function of being able to tune the parameters by artificial system for example, the width of the confining potentials, the separation between sites the depth of the potential since it's an artificial system you kind of have a playground of tunable parameters. And what we find are two distinct regimes, one which is metallic and one which is anti ferromagnetic. What's key here is that because we have broken sub lattice symmetry and half filling live predicted a spin polarized ground state, meaning that the total spin of the ground state was proportional to the difference in sub lattice a and B. In the weekly interacting regime we have a metallic phase but since our system is still spin polarized we observed that the extra electrons occupy the edge of the system. And in the strongly interacting regime where you over T is large. We have an anti ferromagnetic insulator. So this was just mean field calculations, we then took it a step further and did included correlations in the system. What we found is as a function of filling of the system at half billing, we had a spin polarized ground state, and away from half filling, you get a dramatic drop in the energy gap and other lower spin states emerge in the system effectively becoming kind of like we'll say a button for turning on magnetic properties are turning it off. And that's all I wanted to say, these results are published and if you want more details. The answer saline the University of Ottawa, and I will put my email in the chat and I kind of wish I was in Rome, so everyone enjoy room. Thank you very much. Thank you. Yes, sir. Next speaker more that's a solid. Hello. Yes, yes we can. Okay, let me to share my screen. Please go ahead and share. I cannot share my skin. I think the other screen is now broadcasting. So there's a green button that says share screen. If you click on it, it should. You should be able to share. Can anyone see my screen now. No, no, no. Yes, sir screen is no broadcasting. Please. No, you stop sharing. How to solve the problem. Sure yours. It's not working. Maybe. I don't know how to solve the problem. Maybe you can restart. But my, maybe you can restart your zoom and the meantime, we will go to make speaker. Please stop your sharing. He stopped sharing cold. Next speaker. So our car. So our car, please. Next one here. Next speaker. Jamie Lee. Say yes, the. Hello. Hello. Can you see my screen? Not now, but something has started. No, we cannot see anything. Is that okay? Nope. No, now it's okay. Yeah, go ahead, please. Go ahead. We are setting the digital versus non digit JPA is gain and application quantum. Two modes squeeze rather JPA is Josephson's and parametric amplifier. Here you can see. Here you can see the schematic representation of the quantum. Two modes squeeze rather or QTMS rather JPA is that the heart of the quantum brother that produce entangled signal and Euler. We either can have a digital rate JPA, which has a signal and Euler, maybe the same frequency or a non-digital rate JPA that there's a small difference between their frequencies. Here we show that using a non-digital JPA is going to improve the performance of quantum brother. Our evidences for this claim are shown here in this graph here. For example, in figure two, you can see that. We show these two solid lines. They are for maximum and minimum gains for degenerate JPA. But as you see, the dotted line on top is for non-digital JPA gain for Euler. So here is the first evidence that say degenerate JPA works better. Another evidence comes from SNR, which is signal to noise ratio. And as you see here, the non-degenerate one works better. And this is versus the number of modes. The other one, which was in figure four, then the left side is for degenerate one and the right one is for non-degenerate one. Here we use the quality factor in thermal one, which is fixed between these two, but we increase the external quality factor. And at the same time, we are calculating gain. Sorry time is running, so maybe you can just summarize quickly what's in the poster. I think that this non-degenerate one works better because higher Q value means lower loss. Therefore, when we have lower loss, which is desired for quantum brothers, we have higher gain as you can see here. So these are our evidence to show that non-degenerate JPA works better for the quantum brothers. If I have time, I can talk about my second poster or not? No, unfortunately, sorry. We need to move on. Here is my information if you can give me a comment or discuss. Thank you. Thank you. Thank you very much. Thank you. Next speaker, Musa Mil Shah. Not here. Next speaker, Mustafa Sayed Ahmed Shalabin. Ahmed Shalabin, not here. Next speaker, Shaliyah Sharma. Shaliyah Sharma, please. Yeah, we can see your screen. Yeah, please go ahead. We can hear you. Okay. Yes. Can you speak up a little bit please? Yes, please. Can you say it? Hi, I'm Shaliyah Sharma from IIT, Mandi, India. I will present our work, electronic properties of palladium-intercollated dysmetalluride topological insulator. So, motivation for our present work is palladium is a high Z element and shows exchange enhanced magnetic susceptibility. So, we have studied evolution of electronic properties and topological surface state properties upon palladium-dropic in dysmetalluride. And here we see this resistivity of these caristors show metallic dependence upon low temperature and this high resistivity shows electronic majority charge carriers for dysmetalluride and increase its changes to P type upon palladium-doping. And here we see this magnetic resistance decreases upon palladium-doping. And here we have analyzed the Shubnikov-Bihar's quantum oscillation using Lipschitz-Karswisch theory. And we further performed artist measurements along the gamma N direction and here we see that this tickets a narrow line width for dysmetalluride. And this, here we see this bulk Wellesband as well as this direct point energy shifts towards the Fermi level upon P-D-doping. This is well in conformity with the Hall data that shows N to P type crossover upon palladium-doping. And here we see this hexagonal warping is then decreases upon palladium-doping and it turns towards Mohr's circular. And therefore taken together this STH data and RPS results, we see that there is a reduction in Fermi wave vector from STH data and this reduction is due to the band bending effect. And this band bending effect is induced by the Schottky barriers at the metal semiconductor interface and this is inevitable for the magnetic transport measurements. So, overall these studies discuss correspondence in parameters obtained from RPS and magnetic transport results. And for more details, you can follow this paper or write to him. Thank you. Thank you. Next speaker, Gabriel Moreira Suza. Hi, can you. Hi, can you. Yes, we can. We can hear you but we don't see your screen. Now can see. Now we can see your screen. Go ahead, please. Okay. Thank you very much. My name is one. I'm about effective the tip for fractals. The model I'm working with. Okay. The model I'm working with is what's first proposed as a fragile like quantum glass by Cassano Benchamon. It is defining HCP lattice. It is described by the this Hamiltonian one in which we are prism operators defining here. And the properties of this model are it is exactly solvable. The eigenvalues are plus or minus one. Therefore, the eigenstates when all the people prioritize eigenvalues plus one, and the model is get it. The most interesting properties are the mobility properties in this direction the expectations are mobile while in the x y plane the expectations are fully mobile they are fractals. In order not to annihilate free excitations, we see that the formation of fractal membrane characterizing it as a type two factor. So to construct an effective theory, we propose these gauge fields with these gauge transformations, and we can see that it presents the desired profits because if we study the interaction action, we see that there are two charts. We have seven charts Q and QF and QF shows the desired property about the fractal behavior because F is an harmonic function. This is what I have very much. Thank you. Thank you very much. Thank you. Next speaker. Malik. So, yes, we can hear you. Please share the screen. Hello. Can you hear me? Yes, we can hear you, but we don't hear screen. Let me share my screen. Please. Please share the screen Malik. Malik, we cannot see your screen. Maybe you can just restart zoom and in the meantime we'll move to next person and then we'll come back. Let's move to the next speaker. Samudra Sur. Yes, please pick up and share your screen. Yeah. Now, am I audible? Yes, yes, go ahead. Okay. So, I'm going to talk about driven Hubbard model on triangular lattice. This is a portable Heisenberg antiferromagnet with three spin current term. So in this work, we have studied the interplay of periodic driving on a strongly interacting electronic system on a triangular lattice. So we start with a half field Hubbard model on a triangular lattice, and we drive it with an electric field which is in plane to it, and the form explicitly breaks the time reversal symmetry. So we incorporate this electric field into the system, following parts prescription by adding a phase in the hopping term. And we use a theory called floquet perturbation theory in the limit that the hopping terms are much less than the interaction. Then we see the low energy excitations are described by the photon assisted virtual hopping in the nearest neighbor sites. And using this floquet perturbation theory up to third order, we derive an effective spin model, which has nearest neighbor Heisenberg couplings, which is an isotropic in three different directions, and also a chiral three spin term which has plus and minus sign for up and down pointing triangles. So these couplings of this effective model j alpha j beta j gamma and see can be tuned by the driving parameters, which are the amplitudes of the electric fields e one e two, the frequency of the field and the angle of the electric field theta. So here it is shown for some values of amplitudes and frequency how the couplings vary with the angle of the field. And from see vanishes if they if the driving field is time reversal symmetric. Now from this effective Hamiltonian, we do an exact diagonalization on a six cross six lattice system with periodic boundary conditions, and to reduce the Hilbert space to attractable form we use the symmetries of zero magnetization spin inversion and simultaneous parity inversion along x and y axis if C is zero. And then we study the different ground states of this model using the spin structure function. And we find that there are four types of ground states of them. So four types of ordered ground states in the system of them three are collinear and one is co planner of 120 degrees time. And we also have three type of spin liquid ground states. And we also found find the phase boundaries using using fidelity susceptibility real space correlation and energy gaps. And here we show the phase diagram. We have these seven phases of these four are ordered and three are spin liquid. So, and this is a work which is published in PRB this year. Thank you. Thank you very much. Thank you. Thank you. Please, I think it is okay to screen to share my screen. Malik so Samudra please. If you can just go ahead and share your screen. Yes, go ahead. Samudra please stop. Yeah. Malik so go ahead. Unfortunately, it doesn't work. And if we cannot see your screen. And now maybe something is going on. Unfortunately, it's probably bad connection because it started and then crashed. Let's try. Yeah, maybe you can just say what's the, what's your title and in few words what the poster is about. Could you describe your poster in just a word and simple words. Yeah, I guess the screen is frozen. Okay, let's move on. Yeah, we need more fun. Next speaker Jill swami Jill swami. Not here. Emanuel. Emanuel. Not here. Shannon way. Yes, go ahead. Yeah. Hello, I'm trying. I'm going to show how the strength mental phase appears in disorder just by the graph and how this is the relate to the with the couple that's like a bundles. I just want to understand the relationship between the second phase and the strength mental phase in the two spedigraphy. I didn't know that the medical and go to spedigraphy hybrid sevens, our idea is to break the flabons into bundles to break flabons column disorder is introduced. The potential craze puddles, intuitively localized flabons are just trapped by these puddles inside each puddle, which is also, which will also becomes a slightly bundle, the interaction of the sevens just to make them, make them interact with each other, creating an auto interaction, just like to select behavior, and the bundles are also actually interacting with each other. The specific heat is computed at low temperature, showing this like a behavior. I'm here by computing the auto time or the creator, they have enough exponent of the, and the bath lab lost it is also extracted. We can see that at low temperature, the level of exponent is just linear in temperature, which is a typical behavior of the strength metal. Also, the bath lab lost it shows a non familiar type of temperature scale, which scales as to to the some power, which is larger than one. All this concludes the chaotic strength metal phase, also at week disorder. As one can expect, the system recovers the connectivity and the auto time or decorator just show the exponential decay. As a result of all this, we come to the face diagram, just like this. Thanks for attention. Thank you. Thank you channel. Next speaker. Hello, can you hear me. Yes, we can. Okay. Share screen please. Yes. Is it okay now. Okay, yes. Good. Yes, go ahead please. Thank you. Hello everyone. My name is Razia and I'm here today to talk about some of the interesting features of a small bit couple junction. Based on graphing to get started, I want to propose a junction as you can see in the figure made up to for magnetic region and spin orbit coupling layer between them, which is always on a graph and layer. And, you know, both magnetism and spin orbit coupling can induce into their graph and layer by proximity effects. So we have a very good setup to actually to changing the orientation of magnetization to produce a spin or ice current. And the spin torque exerted on the junction we considered this situation that the bias will face right particles from the left for magnetic region into the right one. So, so if we consider the effective Hamiltonian, like this equation for each three regions and boundary conditions at x equal to zero and D. And then calculate the what the wave functions and other parameters we can study the closet particles reflections and transmissions. And then other features like spin torque spin conductance and spin turn problems. So you can see in this figure that that it is the main result of this study. The spin transfer torque as a function of spherical angles of magnetization in the for magnetic region. So, so when particles hit the interface is perpendicularly the simple arise direct fermions transmit perfectly through the boundaries of junction and, and the spin transfer is often zero. So in the presence of the spin orbit coupling and non zero spin transfer torque we appears because of the event the structure modification. And, and finally we hope that these findings can be applied in the proximity in the spin orbit coupling graph and system experiment. In this discussion can contact us with this email others and see the original version of our article in the archive. Thank you for. Thank you very much. Thank you. Thank you. Next speaker for note. I'm sorry. Hello, you can hear me. Yes. Yes. I have some problems. Let me correct it. Excuse me. Can you see my screen. No. If I have time I will go to next one and then you will try to fix the problem. Let's go to the next one. Good. Next speaker. Get out on all of my, all of my, you know, get out on all of my, you know, here. Next speaker Ahmed chaff I not here. So anyone from the previous speakers who had technical difficulties. Anyone wants to present. I think just my presentation is remained. Yes. Yes. Go ahead try. Okay. Maybe describe it in just words. Try again. Okay, I can talk it in audio. No, no problem. I can do it. Please go ahead. I have a question. I have recently ended post that period I have worked on several questions about many body and transport properties of force worrying which is highly on isotropic monolayer material. For London family liquid in its most most on isotropic version. It is well known that in line wavelengths limit and finite frequency of external perturbation the current density within linear response regime is equal to viscoelastic model of electron liquid. A question is that, what is the elasticity hydrodynamic correspondence would be in the case of on isotropic liquid, like that of force for this question then arrays. What is the appropriate hydrodynamic model for 2D electrons in general, and especially for force for in as an orthorhombic to the two dimensional London family liquid which can go further to find viscoelastic model for a generic on isotropic viscoelastic dynamic equations with 18 independent risk elastic module and the solution within the solution the Christopher matrix and metric tensor immerse, immerse out naturally and put it in equivalence in line wavelengths limit to the microscopic theory of the of our microscopic theory by means of the exchange correlation kernel and go beyond the random phase approximation and modify their RPA plasma. See that the gravity theory is here efficiently image out as an viscoelastic version. This rings the bell in the mind for a holographic duality viscoelasticity as the gravity and microscopic theory as our field theory and then let me briefly discuss about my motivations which this time. Yeah. Thank you very much. I put my contact your email address yes. Thanks very much for the problem. Thank you. Thank you. Thank you very much. So this concludes our poster discussion section. Thanks to everyone.
