Hello everybody, I have three quite mathematical questions in modern QFT. 1) Why it's supposed that N=2 SUSY Yang-Mills probably cannot be put on a lattice? 2) What is the recent status of lattice approach to conformal quantum field theories? This question is motivated by the following...

Thank you for your reply, I have never seen these papers; it seems they are very interesting. Unfortunately I have no good supervisors for doing ADS/CFT in my city. For now I'm interested in AGT conjecture and some integrable models.

Hello everybody! I recently started to work in nonperturbative QFT (especially CFT and SUSY models). I love my work but wonder what is the recent development in this subject beyond the SM? It is not hard to see that at the dawn of XX - early 2000's the most exciting results in nonperturbative...

Thank you for this advice, Coleman is really good!

Hello everybody! I've recently decided that I'm interested in supersymmetric solitons and want to work in this area for future 2 undergrad years. I wonder what is the best place to study the general theory of solitons in QFT? Is Rubakov "Classical gauge fields" really the best book for those who...

Thank you!

Hello everybody. I'm interested in some problems of bound states in external fields in QFT (especially QED). I wonder are there any lectures/books or reviews which provide modern treatment of this subject? I would like to learn more about general formalism and applications in QED (I allready...

I think I should change "unfounded" by "not sufficiently founded in my opinion".

Hello everybody. I've recently finished work through Weinberg's course in QFT which made my understanding of theoretical physics quite peculiar. For example, I can't understand statistical physics from Landau&Lifshitz book at all as there are a lot of unfounded arguments. I wonder firstly is it...

Weinberg gives detailed explanation of why we need gauge invariance to construct QED in his book (vol.I section 5.9). You may find it nice enough.

Your advices are wise, thank you. I think I really should reconcile and start to work with our groups despite I'm not very interested in their works. Maybe you can advice me some literature on CMT (or general quantum theory of many body) which emphases connections with modern QFT, CFT and...

Thank you. I know about these relationships between CMT and QFT and I find them very beautiful as you do. Unfortunately, our cosmologists don't use GR in their researchers, and condensed matter theorists don't know modern QFT. They make interesting researchers, but they are old-fashioned and...

But also (as i think) it is a good pedagogical book for physicists

I see. How do you think is it usefull for my purposes to start work with different theoretical groups? There are several good groups in astrophysics and condensed matter physics in my city. Some of their researches seem to me too boring but I have no other choice (according to your words)

Thank you for your answer! Of course I will finish my undergraduate degree. But what should I do to be accepted ? They might think I'm just an ordinary but too ambitious student.
