Advanced quantum theory, Lecture 14

This summer semester (2016) I am giving a course on advanced quantum theory. This course is intended for theorists with familiarity with basic textbook single-particle quantum mechanics. The main objective is to understand how to study many interacting particles within QM. We will cover second quantisation, scattering theory, and some elementary relativistic quantum mechanics.

Here in Lecture 14 I continue the discussion of the S-matrix and introduce the scattering cross section.
