Prerequisites: Quantum Mechanics, Statistical Physics, Solid State Theory

The aim of this course is to learn basic methods of modern many-body theory and to apply them to various problems in condensed matter physics. At the end of the course students should be familiar with the tools to follow current research topics and be able to start independent research.

Topics:

  1. Second quantization & applications
    (Hubbard- and Heisenberg models, SDW mean-field theory, weakly interacting bosons, BCS-theory of superconductivity)
  2. Functional integrals
    (Path-integral representation of the partition function, correlation functions)
  3. Diagrammatic perturbation theory
    (Feynman diagrams, Hartree-Fock, RPA, screening and plasmons)
  4. Linear response and Kubo formula
    (analytic properties of correlation functions, dielectric function, conductivity of disordered metals)
  5. Hubbard-Stratonovich transformation, collective modes

Useful Literature:

A. Altland, B. Simons: "Condensed Matter Field Theory"
J.W. Negele, H. Orland: "Quantum Many-Particle Systems"
G.D. Mahan: "Many-particle physics"
A. Auerbach: "Interacting Electrons and Quantum Magnetism"

additional literature on special topics will be announced in the lecture

Credits/Exam:

9 ETCS credits. There will be a written exam on Tue., July 24th at 10:00. Details will be announced in due time.
