Condensed Matter Theory II:

The complexity of 1023 particles interacting with each other in a solid give rise to many emergent phenomena one would not predict from the simple interactions between two electrons. In this lecture we will, starting from simple models and theories work our way into the contemporary theory of many particle physics.

The lecture builds on the concepts discussed during the condensed matter physics I lecture series. We will use these to look at interacting many body systems.

Background knowledge assumed to be present:

(you can find these topics in the lecture notes, look at youtube videos of the previous lectures or ask during the lectures for more information)

Second quantization
Tight binding representation of Hamiltonians and how to solve the band-structure (Fourier transform, crystal momentum)
Green's functions for non-interacting system and Dyson equation to calcualte impurity or surface states.

Concepts of many particle systems discused are:

Response functions.
The difference in response functions between interacting and non-interacting systems.
Green's functions and diagramatic expansions for interacting systems.
