Condensed Matter Theory II
Condensed Matter Theory I:
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 topics discussed in CMT I. In CMT II we will focus on interacting systems.
Concepts of many particle systems discused are:
- Green's functions
- Response theory
- Finite temperature, phase transitions and Matsubara frequency
- Effective Hamiltonians
- Dynamical mean-field theory
- Electron phonon coupling
- Superconductivety
