Summer term 2017, Lecture:
Symmetries and particle physics
These lectures are intended for Master students of physics. The implications of symmetry in physics are ubiquitous and very interesting. Mathematically, they are described by group theory. I will start from finite groups and then disuss the most important Lie groups and Lie algebras, in particular SU(2), SU(3), the Lorentz and Poincaré groups, the conformal group and grand unification.
Tuesdays, 11:15 - 13:00 h, Philosophenweg 19, Seminar Room.

TEACHING IN PREVIOUS TERMS:
Winter term 2016/2017, Master-Seminar:
Relativistic fluid dynamics for heavy ion collisions and cosmology
The seminar is intended for Master students of physics. We will discuss different aspects of relativistic fluid dynamics (in a wide sense). This includes theoretical aspects such as the relativistic Navier-Stokes theory (and its problems), second order theories like the one of Israel & Stewart, applications to heavy ion collisions, but also aspects of fluid dynamics in the context of cosmology and structure formation.
Fridays, 14:15 - 16:00 h, Philosophenweg 12, kleiner Hörsaal.

Summer term 2016, Lecture:
These lectures are intentended for Batchelor and Master students of physics. They will start with the basics of fluid dynamics which rely on the conservation laws for energy, momentum and particle numbers as well as thermodynamics. The most important equations of fluid dynamics will be discussed as well as the phenomena they describe. More advanced topics will be turbulence and superfluidity as well as applications of fluid dynamics in current physics research, for example in the context of heavy ion physics and cosmology.
Mondays, starting from April 18th, 11:15 - 13:00 h, Philosophenweg 12, großer Hörsaal.
There was a written exam on Monday, July 25th from 11:30h to 13:00h. Results can be found here.
