Master and Bachelor Thesis Topics

We are offering a range of topics for Bachelor and Master thesis from these specific research areas:

• Transport, nonequilibrium physics and dynamics of electron-phonon systems
• Semiclassical methods for the theoretical description of electron-phonon systems
• Thermalization in closed quantum systems including eigenstate thermalization hypothesis, many-body localization and constrained dynamics
• Many-body physics with ultracold atomic gases
• Topology in many-body systems, in particular, focussing on realizations with ultracold atomic gases.

All topics make use of computational methods such as exact diagonalization, Lanczos methods, or density matrix renormalization group techniques. Students will write their codes from scratch. The concrete topics are embedded into the group's ongoing research projects and are each co-supervised by a PhD student or a postdoctoral researcher. For inquiries about concrete topics, please contact the group leader Prof. Heidrich-Meisner via email.
