Assignment to Modules

Further Information

Courses are together with exams the building blocks for modules. Please keep in mind that information on the contents, learning outcomes and, especially examination conditions are given on the module level only – see section "Assignment to Modules" above.

additional remarks This course will focus on recent progress in realizing strongly-correlated many-body systems with ultracold atoms. Both theoretical ideas and recent experimental results will be reviewed. Throughout the class the relations between many-body systems of ultracold atoms and condensed matter will be emphasized. We will also discuss unique features of ultracold atomic systems, such as control of band structures and interaction, availability of new probes, and the possibility to study nonequilibrium quantum dynamics and disordered quantum systems. A tentative outline of lectures: 1) Introduction to many-body physics with cold atoms 2) Bose-Einstein condensation of weakly interacting atoms 3) Noninteracting atoms in optical lattices: Engineering band structures and topological states 4) Interacting lattice bosons: phase diagram and nonequilibrium dynamics 5) Low energy collisions and Feshbach resonances 6) Ultracold Fermi gases: BEC-BCS crossover 7) Realizing quantum impurity systems with cold atoms: orthogonality catastrophe and beyond 8) Quantum magnetism with ultracold atoms 9) Interferometric probes of many-body systems 10) Disordered and interacting many-body systems: Many-body localization The practical classes support the lectures with tutorials and problem sets. The tutorials cover basic theoretical concepts of many-body physics such as an (i) introduction to second quantization, (ii) Green's functions and linear response theory, and (iii) Fermi's Golden rule, etc. The problem sets will help to understand and deepen the physical concepts presented in the lecture.

Condensed Matter

When atoms interact things can get interesting. Fundamental research on the underlying properties of materials and nanostructures and exploration of the potential they provide for applications.

Nuclei, Particles, Astrophysics

A journey of discovery to understanding our world at the subatomic scale, from the nuclei inside atoms down to the most elementary building blocks of matter. Are you ready for the adventure?

Biophysics

Biological systems, from proteins to living cells and organisms, obey physical principles. Our research groups in biophysics shape one of Germany's largest scientific clusters in this area.
