Are there good references for (both zero and finite time) interacting systems of quantum many-body theory? More precisely, I would be interested in references discussing the following topics: 1. Second quantization 2. Zero and finite time Green's function (time-ordered two point function) and its relation to spectra of the full Hamiltonian (i.e. with interacting term) 3. Perturbation theory (e.g. [Gellmann and Low formula][1], Wick's theorem etc) 4. Linear response theory These are some standard topics in physics books about many-body quantum mechanics. I am basically looking for rigorous justification of (at least some) of the most important formulas in the physics textbooks about these topics using good functional analysis. **Disclaimer:** I don't know to what degree the topics above are well-developed from the mathematical point of view. I am assuming one can get pretty far and cover a lot (if not every) topic using functional analysis and related techniques, in the spirit of Reed & Simon.
