General lecture: Geometry and topology in quantum physics

lecturer: Prof. J. Budich (TUD)
time: Mondays 16:40-18:10, Tuesdays 14:50-16:20 
location: BZW A120 Zellescher Weg 17 (Mondays) SE2/103 (Tuesdays)
content: 

In this lecture, we discuss the role of geometry and topology in quantum physics. We start with a both phenomenological and formal treatment of geometric (Berry) phases. Building up on these concepts, we study in the framework of quantum many-body physics the theory of topological phases such as topological insulators and superconductors as well as bosonic symmetry protected topological phases.

 

format: Every 4th lecture will be a tutorial session.

General lecture: Chaos in higher-dimensional systems

lecturer: Prof. Dr. A. Bäcker (TUD)
time: Mondays 11:10-12:40 , Tuesdays 11:10-12:40 
location: BZW A120 Zellescher Weg 17
content: 

Many physical systems of interest have more than two degrees of freedom which can lead to highly complicated dynamical behavior. Examples are the solar system, atoms and molecules or particle accelerators. In this course we give a general introduction to the dynamics of such higher--dimensional systems. Central for the understanding are invariant objects like fixed points, periodic trajectories, invariant tori, and stable and unstable manifolds. So-called non-linear resonances play a crucial role as they are at the heart of the famous Arnold diffusion, which exclusively occurs in higher-dimensional systems. The course will be based both on rigorous mathematical results (including ideas of their proofs), and results of numerical investigations.

 

format: Every 4th lecture will be a tutorial session.
