 for the next hour. We've provided, actually my colleague, Alex, mostly put this tutorial together, who's now in the other hall. It provides very concrete kind of instructions. And right, if you have questions, just let us know, but I'm just gonna walk around and see if you have questions. Okay, so the goal of this tutorial is to compute one point of this kind of face diagram. This is a kind of finite temperature of lanthanum-coop rate at zero doping. This is a very simple one-band model, which has like two-dimensional kind of square sheets. You have one electron per copper atom, and this has mainly DXY, Y-square character. And we're gonna look at this kind of paramagnetic regime in DMFT. And you can see the change in the density of states, in the spectral function, between the one-unit density of states and the correlated spectrum. So this is kind of the goal of this tutorial. I also want to thank the organizers, in particular Junfin, bless you, Junfin and Giovanni for taking care of setting up the software infrastructure and for the great communication. And right, I think that's all that I wanted to say. So here kind of the instructions, how to get started, and then let me know how things are going. Good luck. And also, I think the solutions are actually also somewhere, but we take it that you do this as you wish what you want to learn. But in case you get stuck somewhere. Can you hear me over there? Yes. Very good. So I'm also here now. Great. So I came a bit late. Did you mention that people might use the metrics chat to answer, to ask questions? Okay. Sophie, can you hear me? Yes. Okay, just wanted to check that we could hear you here at Adriatico, that's all good. Thanks. How's it going over there? Fine. Oh, good. Good. Actually, you can see. You can try it. But now you're not into this. Sorry, sorry. Sorry. Sorry. And then you go there. There, type of the same thing. So you're going to do this. I'm going to do this by now. So I'm going to name you a sign. Yeah. I'm going to use this email. So both the software and the text. Yes, it starts with you. I see. Yes. Yeah. I think I have one access as a user. I mean, I think she can use it right. If I give her the link and the password, she can use it. Ah, yeah, yeah. You can, yeah, yeah. So your own build for machine. Yeah. Yeah, absolutely. Yes. So for those of you who get this error that lco-dos.dat is not found, you have to delete your tricks. This, delete step three, this directory and copy it new. Because we had to change something in yesterday, so. Oh, yeah. You can. Right. You can. You can. You can. So I think, please, I guess she receives now the mail. Okay. That's good. And she could, she could upload access. I, she now uses my one. Okay. Then from the phone, she can use. Okay. Okay. Oh, yeah, you can. Oh, yeah. You can use your phone. Then just decided to run. So that's why. So you will not use structured. I don't know if that's actually something we saw in the last few days, things that are hard for the public to judge much, but in the last few days we've tried to, like, uh, it's like... But I think that you really have to think about... Eyes. Eyes. Eyes. Eyes. Eyes. Eyes. Eyes. Eyes, I think. Yeah, that's basically a question about how I need to... Just to clarify – if you end up at step six, uh, you have to open a new terminal, again type source, Tricks, Activate, and then before you launch the DMFD. You have to enter the same directory – day three AM, Tricks. So, if you have it stored somewhere, type dot, and then it will be the second thing that you can do with it, no, I'm in the, ah, yes, so you can access them as, at least they won't in this fall. But this is just, okay, I think I know how it's going to look like. Yeah, that's not so all. I didn't, I didn't wrote that part, so, okay. Yeah, there was one question on Zoom, I think she's, so she's taking care of that. I'm trying. Oh, the mic is on, sorry. No worries. Alex, do you have a solution for this? I think it must mean that a prior step was not executed properly. Then she's, is the mic on? Yeah, yeah. Someone is using our virtual machine, so you cannot access there right now. Okay, okay. But Alex, do you know what, what the problem is that? But it isn't a wrong directory in the Python notebook or something. Okay, I would like to share where it is, but I don't know how to, yeah. I mean, now she has her own credentials, so she could use her own. You switch to yours. No, no, leave it like this right now. I mean, no, I think it's good. It's good. She has finally everything open. So, but where is the error occurring? I'm not sure what, what step 13 is. Well, when we create the HH5 archive, I guess. Yeah, there are some commands around it to change the directory and maybe some of them went wrong. If she restarts the whole Jupyter notebook and just executes it from the top, it should work. Did she start the Jupyter notebook in the right directory? Because it assumes that the that the directory where you started is the directory of the root of the tutorial. Alex, can you see this error? It looks like a wasp. Alex, can you hear me? Yeah, yeah, we can hear. But like, what does, what does, what does this have to do with the tutorial? Nothing. Okay. So this looks like this is a wasp output, right? Yeah, we're not running wasp here. We're only using quantum express. But the error is appearing in Jupyter, right? I mean, maybe she can. Yes, she already noticed. Maybe, maybe, yes. Could she, could you maybe also use the metrics chat? Then I can also follow. Okay, we'll try to switch there. Alex, so this is the error message now. Yes. So it's as, as expected, like the Jupyter notebook, I think it's not in the right directory and it's also read only. So. Ah, yes. So I think step, step two was somehow skipped. No, step three, where you copy the tutorial into your local directory. Using the first line, no such file was found. So you have to close your Jupyter kernel copy from where you try to execute it into your local directory and start again. I think we're kind of running a little bit over time already. I think it's basically time to, to get lunch. Feel free to continue working in this in case you haven't finished and, and continue to ask us questions. Otherwise, I think you're free to go. Well, you were anyway. Thanks for, for participating.
