Dynamics of cold atomic gases
Thomas Gasenzer
Wednesday, 09:1510:45, INF 227 SR 3.401, Start: 18 April 2007
Content:

Introduction
(Atomic BoseEinstein condensates and (degenerate) Fermi gases, experiments,
observables)

Introduction to mean field theory
(GrossPitaevskii dynamics, hydrodynamics, excitations near equilibrium)

Dynamics close to equilibrium beyond mean field
(Boltzmann's kinetic theory, kinetic theory of BoseEinstein condensates, Beliaev theory, Landau damping)

Quantum field theory far from equilibrium
(Path integral approach, effective action, 2PI theory, perturbation theory and loop expansion, 1/N resummation)

Applications and phenomena
(Equilibration, classical vs. quantum dynamics, classical simulations, dynamics near phase transitions)
Prerequisites:

Quantum Mechanics (Theoretical Physics III), Statistical Mechanics (Theor. Phys. IV)

Quantum field theory, Path integrals in Quantum Physics would be helpful for the second part of the lecture.
