This course aims at giving an introduction the quantum liquid Helium 4.
After a recap of Thermodynamics and ideal Quantum gases, first, the well verified experimental phenomena which are shown by superfluid Helium4 are presented. Then the Tisza-Landau two-fluid models and related generalizations will be discussed. Depending on how much time there will be, we will also discuss more recent results of Quantum Turbulence (HVBK equations, Vortex Filament Method) and the degenerated Bose Gas.
Non-repeated universal elective course.
