Content, Learning Outcome and Preconditions
This module covers advanced topics of ultracold quantum gas physics. Both the fundamental concepts and experimental work and concepts are described. Topics discussed include a detailed discussion of the physics of degenerate Fermi gases both with and without interactions. The interactions of quantum particles are explored, including Feshbach resonances and the unitary regime of Fermi gases, as well as Cooper pairing in the Bardeen-Cooper-Schrieffer (BCS) limit and the BEC-BCS crossover to the Bose Einstein condensate (BEC). Another section discusses interacting quantum gases in optical lattices, the Fermi-Hubbard model, quantum magnetism and lattice geometries beyond the square lattice. In addition, selected of modern areas of the quantum gas research field are discussed, such as for example synthetic gauge fields, low-dimensional quantum systems, long-range interactions, orbital quantum gases and quantum gas microscopy.
After successful completion of the module the students are able to:
- Understand the physics of Fermi gases and apply related methods such as the Sommerfeld expansion.
- Discuss interacting Fermi gases and their quantum phase such as the BEC and the BCS limit.
- Explain various fundamental methods in quantum gas preparation, manipulation and detection of many-body states of the system.
- Describe the effects of quantum statistics on ultracold gases 5. Understand the effects of interactions on quantum gases with internal degree of freedom.
No preconditions in addition to the requirements for the general Master’s program in Physics, in particular no other quantum gas classes are required.

Learning and Teaching Methods
Description of exams and course work
There will be a written exam of 120 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
- Derivation of simple relationships and models such as the Sommerfeld approximation, or scattering phases
- Explanation of phenomena such as superfluidity in fermionic gases
- Discussion of the properties of the BEC-BCS crossover and derivation of related quantities
- Calculation of simple few-particle models such as interactions and dynamics of particles in potential wells
- Discussion of insulating and conductive behavior in lattices, and derivation of lattice properties such as band structures
- Explanation and derivation of resonance phenomena in interacting particles
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
The exam may be repeated at the end of the semester.
