Hey

Im taking this course, which is following the book "Many-body Quantum theory in condensed matter physics" by K. Flensberg and Bruus. It basicly covers:

Second Quantization
Mean field theory
Linear Response theory
Normal and imaginary-time greens functions
Equation of motion theory
Feynman diagrams
The interacting electron gas

Im hoping that i perhabs can get a little help on this forum, on a few exercises - next week. But it is a little above, normal university physics i think.

Alternatively, is there any other place where i can find help to these kind of physics problems. I have found some physics tutor websites, but im not really sure if that is what im looking for - or if these websites can be trusted.
