Superconductivity, superfluidity and Bose-Einstein condensation 1102-6`BEC

The lecture is an introduction into many-body physics where quantum coherence is present on a macroscopic scale. We discuss both phenomenological and microscopic theories of superconductivity and superfluidity within a single conceptual framework of a generalized Bose-Einstein condensation.

In particular we present: physics of low and high temperature superconductors, elements of the Bardeen-Cooper-Schrieffer theory for paired electrons, Ginzburg-Landau theory of superconductors, symmetry breaking in superconductors, Anderson-Higgs mechanism and its relation to Meissner effect and London theory, physics of superfluid helium four, two fluid phenomenological description, Landau criterium for superfluidity, Bogoliubov theory of superfluid bosons, extensions of Bogoliubov theory, physics of superfluid helium three, phenomenological approach and microscopic classification of phases of helium three, physics of Bose-Einstein condensed ultracold atoms in magneto-optical traps and optical lattices, physics and microscopic theories of vortex states for different condensates of fermions or bosons.

To follow the lectures students are requested to know: quantum mechanics, electrodynamics, statistical physics with thermodynamics.
