402-0861-00L Statistical Physics
|Semester||Autumn Semester 2016|
|Periodicity||yearly recurring course|
|Language of instruction||English|
|Abstract||This lecture covers the concepts of classical and quantum statistical physics, and some aspects of kinetic gas theory and hydrodynamics. In a more advanced part degenerate Fermions, Bose-Einstein condensation, real Bose gases, magnetism, general mean field theory and critical phenomena will be addressed.|
|Objective||This lecture gives an introduction in the basic concepts and applications of statistical physics for the general use in physics and, in particular, as a preparation for the theoretical solid state physics education.|
|Content||Basics of phenomenological thermodynamics, three laws of thermodynamics.|
Basics of kinetic gas theory: conservation laws, H-theorem, Boltzmann-Equations, Maxwell distribution.
Classical statistical physics: microcanonical ensembles, canonical ensembles and grandcanonical ensembles, applications to simple systems.
Quantum statistical physics: single particle, ideal quantum gases, fermions and bosons.
Degenerate fermions: Fermi gas, electrons in magnetic field.
Bosons: Bose-Einstein condensation, Bogoliubov theory, superfluidity.
Mean field and Landau theory: Ising-, XY-, Heisenberg models, Landau theory of phase transitions, fluctuations.
Critical phenomena: mean field, series expansions, scaling behavior, universality.
Renormalization group: fixed points, simple models.
|Lecture notes||Lecture notes available in german.|
|Literature||No specific book is used for the course. Relevant literature will be given in the course.|
