One of the best sources to learn about a particular subject area in a field of study is to read someone's thesis. In this thesis, in one shot, the author has covered rather well the technique of angle-resolved photoemission spectroscopy (ARPES), many-body physics, BCS superconductivity, Fermi Liquid, and strongly-interacting systems, as applied to the electronic structure of this phenomenon.

It is highly recommended for anyone wanting to learn about any of the areas mentioned above.
