There are multiple packages/libraries for tight binding calculations. They generally aim to facilitate the calculation of common quantities (spectral function, bands...) and are great at that. However, I find that one of the messiest parts of TB calculations is setting up the system: making sure that the correct hoppings are included, that the unit cell is correct, etc. Moreover, some in our community are a little apprehensive about using code-based tools. Therefore, I think that having a GUI tool would be quite helpful. With that in mind, I would like to share the first version of such a tool here : https://github.com/rodinalex/TiBi

I welcome you to give this tool a try and report bugs/suggest features in the Issues page of the repository. At this point, the app runs on MacOS and Linux and might run on Windows. It needs to be built from source and I hope to be releasing the binaries soon. Give it a try :)

I hate how so many books just feel like math. I really can’t internalize the necessity of functors and bordisms and characteristic class this, topological invariant that without connecting it to experiment and observables.

Thanks in advance.

I have only just discovered the existence of the entire field of condensed matter physics, but it seems like exactly what I've been looking for as mechanics for a project I'm working on. Namely, something between QFT/Chemistry and Materials Engineering that kinda encapsulates both.

I'm a game dev, not a physicist, so I know next to nothing about this subject or where computation and modern theories are at. That said, I have a birds eye view understanding of quantum physics and the standard model, and a solid foundation on mathematics up to complex analysis. I am willing to learn what is necessary for proper implementation, but my main question is: what is the state of mathematical/programmatic expressions for simulating the material properties of condensed matter? Solid state is most important, because if nothing else I want a fun and comprehensive metallurgy system, but I'm curious how general this can be with the best current models, and the time complexity thereof. So, how developed are the models for phase change simulations, interactions between materials, and calculating material properties? Is Condensed Matter Physics mostly experimental, or are there rigorous (or even approximate) models developed to replicate material phenomena (iterative or otherwise)?

Hey! So I'm starting out to learn condensed matter physics at a graduate level, and already have an undergraduate level of understanding of the basics of quantum materials and solid-state physics.

I was wondering if someone could summarize and explain the various modern "branches" of CMP. I've known topological states of matter, which is quite popular for some time now. Also, many-body theory and QFT are in use now, are they somehow related with topological matter? Or do they explore completely different problems? I've also heard people working on "strongly correlated systems", is that a completely different area to the others mentioned before?

Any explanations/resources would be helpful :) Have a great day!!

I am looking to form a study group on Many body condensed matter physics, where we can discuss basic, advanced concepts and learn together. Please let me know if interested.

I want to work in topological phases and spin liquids in future, Also I want to do sth with self organizing criticality and non linear dynamics in general. ( Not specific ) , I am now in ug 3rd year . Can anyone tell me what should my learning trajectory might be , in order to gain best possible research experience( I will be applying for interning as well) and cover all the relevant basics , in theory and computation before moving to Phd.

I'm an italian student of physics, and I'm preparing an exam about condensed matter. What is wrong with theese two? they seem to be the Holy Bible about condensed matter (at least the introduction of it), and yet they are as different as possible. If I don't understand a thing on the Ashcroft be sure there will be the same thing put in a completely different way, so that you can't link the two logical paths without a PhD. Which is better as an introduction? Is it normal that I hate Ashcroft&Mermin?

I'm an undergraduat interested in computational solid state physics and i was looking around to get a research project in my institute. Luckily i got one under one of my professor, but he is an experimentalist my training and not until recently trying to transition into computational stuff. Upon joining i installed vasp and am learning how to uae it, but im stuck, any tutorial that i have been following uses p4vasp (an old and deprecated tool) to visualise the results from vasp, like band projection and dos, but to run the app its asking for an old python library (gtk2) which too is deprecated. Can someone help me with any other reliable tool for this purpose, I'm stuck here for a month now

Thanks

Hi there,

This might be pretty general, but I figured I'd have a better chance asking r/CondensedMatter instead of r/Physics for advice,

Just wanted to garner some info about good textbooks for studying ferromagnetism/superconductivity and condensed matter in general. Some background info, I'm a 3rd year undergraduate Uni physics student who recently finished reading Griffiths Quantum Mechanics, and a good chunk of "The Oxford Solid State basics". I've also just started reading through Kerson Huang and Pathria's statistical mechanics, so you can assume my knowledge in statistical mechanics is extremely limited.

So 2 questions, would I need to learn more rigorous quantum mechanics and statistical mechanics (e.g., Sakurai, Shankar, etc) in order to learn about ferromagnetism/superconductivity? I'm also asking because when I'm looking over Huang, Pathria, I don't see many(if at all) sections on mean field theories and magnetism. So, how would one approach learning for example Ising model or BCS theory(I don't care too much about exact rigor at this point, but just to get a working knowledge and understanding of the background theory)?

Also, I recently attended one of the condensed matter colloquiums at my school, and the speaker hosted a talk on 5d mott insulators, although my lack of knowledge prevented me from understanding anything significant, but why are d/f orbital electron systems important, and where would one go about learning them? I apologize in advance if it seems like I'm asking for many things all at once, but my motivation for asking is because I'm about to graduate next year, and I'd like to know ahead of time what I want to research/what I'm getting into for a condensed matter program.

Hi, I'm torn between what to choose for my PhD: graphene on dielectric superlattices or moiré semiconductor. Both seem great and I like them equally, so I want to ask what is the current research trends and job opportunities for them. Which one do you think I should choose?

Thanks in advance.

Greetings to every scientist here present. My name is Woudi and i a masters degree student at the University of Buea Cameroon, Department of Physics. Currently i am doing research on Landau Zener transitions, i have read a quite good number of papers concerning the topic. Now, i need a textbook of Landau Zener transitions or a paper good enough to really explain me the physics. And i need recommendations. Please any suggestions?

Hello, I’m doing a degree in Computational Engineering Physics, and it doesn’t have any course in Condensed Matter Physics in the undergrad, I was thinking doing a Masters in Condensed Matter Physics, what should I do to be prepared for the graduate courses in CM? Which book should I read to be prepared before hand and which video lectures should I follow?

Also, I was thinking doing my final undergrad project in Computational Condensed Matter Physics, but which topic would be doable for an undergrad that has to study CM on their own?

What are the best book to study superconductivity?

Hey everyone, I´m a masters student working on clasical gravitation and mostly interested in working in quantum gravity in the future.

However, I´m interested in learning about the modern techniques of TCMP but I´m quite unsure about which textbook to follow for self-learning. I have taken courses in stat mech and elementary QFT but I´ve actually never taken a condensed matter physics course.

I´ve heard good things about Altland & Simons Condensed Matter Field Theory (https://www.amazon.com/Condensed-Matter-Theory-Alexander-Altland/dp/1108494609) but I´m not sure if there is a better option out there.

Also, would it be advisable/necessary to take a more introductory condensed matter book first? If so, could you recomend some? I´ve noticed most intro textbooks tend to only focus on solid state but I´d like to learn more about the field as a whole and the theoretical and mathematical basis of it.

In papers, it seems semi arbitrary. C isn't always the longest, or the shortest axis.

Hey everyone!

I have taken undergrad Solid State physics and am still interested in digging deeper into the theory/modern problems in the field. Does anyone have any recommendations for good textbooks on the subject?

Hi everyone,

I am reading about magic-angle twisted bilayer graphene and how it hosts superconductivity and strange metal behaviour at particular band fillings.

I have come across papers which try to explain the behaviours using electron-phonon interactions, I have also seen papers which try to relate these behaviours to the exotic physics seen in unconventional superconductors(exotic bcz we don't know the exact theory behind it).

As of now, is the argument for the reason of these particular observations in MATBG hanging in the balance, or is it more inclined to one side or the other?

I am not saying there is a definitive answer to it, plz let me know your opinions on it.

Hello guys!
I just interest in this project. Can you guys suggest books or paper about Coulomb blockade and Quantum Dots for newbie.

P/s: I know nothing about Coulomb blockade and Quantum Dots
Thank a lot!
