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, continue with the framework discussed in CMT I. Starting from simple models and theories work our way into the contemporary theory of many particle physics. 
 
 
Concepts of many particle systems discused are:
  • Surface states
  • Relativistic corrections - spin-orbit coupling
  • Phase transitions and topology
  • Response functions
  • Emerging many-particle states
  • Atomic multiplets, fractional parentage
  • Anderson impurity model, crystal field, ligand field
  • Dynamical mean field theory
  • Magnetism
Theoretical / Mathematical tools used will be
  • Second quantization
  • Green's functions 
  • Self energy 

Levels of theory discussed will be

  • "Exact" diagonalization
  • Diagramatic expansions and partial summations
  • Dynamical mean field theory

Recommended literature

  • Ashcroft / Mermin
    Solid State Physics
  • Kittel
    Introduction to Solid State Physics
  • Mattuck
    A guide to Feynman Diagrams in the Many-Body Problem
  • E.N. Economou
    Green's Functions in Quantum Physics
  • Majlis
    The Quantum Theory of Magnetism
  • Haken / Wolf
    The Physics of Atoms and Quanta

The lecturenotes will be made available as the lecture progressess, they however should not be your only source of information.
