ManyBody Physics, SS 2016
Prof. Matthias PunkLectures: Tuesdays and Thursdays 08:30  10:00 in room A449
Tutorials: Thursdays 15:00  18:00 in room A450 Prerequisites: Quantum Mechanics, Statistical Physics, Solid State Theory
The aim of this course is to learn basic methods of modern manybody theory and to apply them to various problems in condensed matter physics. At the end of the course students should have the tools to follow current research topics and be able to start independent research.
Topics: Second quantization & applications
(Hubbard and Heisenberg models, SDW meanfield theory, weakly interacting bosons, BCStheory of superconductivity)
 Functional integrals
(Pathintegral representation of the partition function, correlation functions)
 Diagrammatic perturbation theory
(Feynman diagrams, HartreeFock, RPA, screening and plasmons)
 Linear response and Kubo formula
(analytic properties of correlation functions, dielectric function, conductivity of disordered metals)
 HubbardStratonovich transformation, collective modes
