3) Fermi polaron, Anderson’s orthogonality catastrophe
II) Quantum Phase Transitions
1) Landau-Ginzburg-Wilson model
2) Superfluid-Mott-Insulator transition
3) Hertz-Millis theory for itinerant magnetism
III) Quantum Hall Effect
1) Incompressibility, Laughlin wave functions
2) Chern-Simons theory and chiral edge states
3) Abelian and non-abelian quasi-particles, Moore-Read state
IV) Topological Phases
1) Topological insulators
2) Majorana Fermions
3) Spin-Ice and ’magnetic monopoles’

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 90 minutes.

Exam Repetition

There is a possibility to take the exam at the end of the semester.

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.
