Content, Learning Outcome and Preconditions

Content

This course provides a modern introduction to many-body physics. It covers basic theoretical methods and their application to various problems of condensed matter theory, such as the interacting electron gas, phonons in solids, quantum magnetism, and superconductivity. Throughout the class relations between experiments and theory will be emphasized. This course will provide students the basic knowledge to follow state-of-the-art research in condensed matter physics and to be able to start their independent research project in that field.

Outline of lectures:
1. Introduction to many-body physics
2. From particles to fields: a route to second quantization
3. Green's functions and their properties
4. Many-body perturbation theory and Feynman path integrals
5. Broken symmetries and collective phenomena
6. Fermi-Liquid theory and the concept of quasi-particles
7. Response functions: a crash course on describing modern experimental techniques
8. Quantum phase transitions

The practical classes support the lectures with tutorials and problem sets. The tutorials provide complementary perspectives  and the problem sets will help to understand and deepen the physical concepts presented in the lecture.

Learning Outcome

This course will provide students the basic knowledge to follow state-of-the-art research in condensed matter physics and to be able to start their independent research project in that field.

Preconditions

No preconditions in addition to the requirements for the Master’s program in Physics.

Module Exam

Description of exams and course work

Problem sets (50%) and final project (50%). Final projects extend the covered material and will be presented 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.
