General Information

Elective for: F4, F4-tf, Pi4
Language of instruction: The course will be given in English


The course shall provide the foundations of statistical physics that is needed both in applications and for studies in theoretical physics. A focus is set on advanced concepts and methods to describe interacting many-particle systems and critical phenomena.
