Only this year


Starting from a microscopic description, the course introduces to the physics of quantum fluids focusing on basic concepts like Bose-Einstein condensation, superfluidity, and Fermi liquid theory.


oncentrating on quantum fluids as basic examples of quantum many body systems in condensed matter physics, I will give an introduction to the physics and phenomena arising due to the interplay of interaction and quantum statistics.
I will focus on the understanding from the microscopic point of view,
based on various theoretical tools from mean-field theory over diagramatic methods to variational and quantum Monte Carlo calculations.




- Basics of statistical physics and quantum mechanics (some reminder)
- Dilute Bose gases: Mean-field treatments and beyond
- Macroscopic quantum effects: Bose-Einstein condensation and superfluidity
- Quasi-two-dimensional Bosons: Kosterlitz Thouless transition
- Normal Fermi liquids
- many-body wave functions


Computational methods and algorithms will be part of the practical work (TP).
