Homework Statement
Problem 3.4e of Peskin & Schroeder Introduction to Quantum Field Theory. Quantize the spinor theory of item (a) of this exercise, where the spinor \chi is the first two components of the Dirac spinor (\psi_L). Find a Hermitean Hamiltonian and the correct...
I was reading Hasan & Kane's review on topological insulators and right in the beginning, page 3, they say that the Bloch ground state is U(N) invariant. I do not see that. Would anyone be able to show it or point to a reference?
Thanks,
Jan.
Kienken,
Just to add a bit of information to Borek's phase diagram in case you have any difficulties, the blue part represents all the solid phases of water. Pick any point in the green area, the liquid phase. If you follow a straight vertical line, you are keeping the temperature constant. By...
I am checking out all the indicated books. The combination of them plus the original papers contains all the information I needed. Thanks a lot everyone for all the help. I really appreciate it!

Thanks a lot. Although I do not have the book and I cannot see the pages, I will borrow it on Monday and take a look.
If anyone else is interested as well , some other friends also indicated me these two books
- Advanced Solid State Physics, P. Phillips
- Methods of Quantum Field Theory...
I have started to learn BCS theory and I am not been able to find a derivation of the effective attractive electron-electron interaction which is assumed to explain the Cooper pairing. Can anyone point me to a reference where I can find this derivation?
Jan.
Graduate level is fine. I have already learned QFT and GR. I'm reading the early papers like Garfinkle, Dowker and Hawking, but I would be happy to find a more detailed, or maybe more pedagogical, description. Rajaraman's "Solitons and Instantons" does not seem to have any black hole pair...
Does anyone could indicate what is the best literature to learn about black hole pair production? Any textbook explaining the instanton derivation in detail for the case of black holes?
