ABSTRACT:
Photoemission is one of the premiere techniques used to study the electronic structure of different forms of matter.
These lectures aim at illustrating how a photoemission experiment can reveal crucial information about the interactions in a many body system. By detecting photoelectrons, a photoemission experiment measures the excitation spectrum of a many body system upon single particle removal and, within certain approximations, provides a direct measurement of the single particle Green function. The lectures will provide a description of these fundamental ideas making use of fundamental notions and techniques of Many Body Theory such as quasiparticles, Green functions, and Feynman diagrams.
