Hi folks, I work in theoretical high energy physics. Recently I got interested in condensed matter theory. But each time I see some spin system I get scared thinking another one must be waiting for me! Can some one suggest me some reference(s) where these spin chains, specially those which are...

Thanks a lot for the reply! Can you please explain it in a bit detail (using required mathematical formalism).

Can some one explain what are the so called "large gauge transformations" and where do they play important role in physics? Explanations with less mathematical rigor will be greatly appreciated.

Can anyone suggest "good" CFT references? Well, by "good" I mean the way they describe the theory are physical rather than mathematical. Actually I want to understand statistical mechanics using CFT as a tool. Thanks in advance!

Now, after reading one of Sachdev's articles I am also finding interest in entanglement entropy and its connection with cond. mat system. Can you suggest some elementary notes/reviews on it?

I have a very basic question: Can AdS/CFT conjecture be applied to field theories without any conformal / Poincare symmetries (non relativistic)??

Actually, the idea is amazing ! But what are your views about its future?

I am learning AdS/CFT and my interest is on condensed matter systems. Can someone tell me what are the achievements of the correspondence in the cond. mat sector till now?

In (3+1) dimension Poincare group has three types of Symmetries : I. Space-time translations - 4 II. Spatial rotations -3 & III. Boosts -3 Among them, (I) implies "conservation of 4-momentum" , (II) implies "conservation of angular momentum" , But...

Thank you very much..! It seems really very useful for me.

I am studying Witten's papers on AdS/CFT. But I don't have any CFT or SUSY background. Can anyone suggest me some lecture notes or books where I can have illustrative ideas on Ads/CFT correspondence? I do have Nastase's notes.It is really good but too short for introduction!
