Within the seminar, students give talks on current topics in condensed matter physics. The seminar aims to give a closer look at new developments in condensed matter physics and to show how these developments can be transferred into applications. The seminar focuses on spin electronics, spin dynamics, solid-state quantum information processing, the physics of solid-state nanostructures, and high temperature superconductivity. These topics are in the focus of several research projects of WMI and collaborative research programs in the Munich area (e.g. the Excellence Cluster "Munich Center for Quantum Science and Technology (MCQST)", the Collaborative Research Center TRR 80, the DFG Priority Program 2137, or the EU Project QMiCS).

The seminar is relevant for the special courses on "Superconductivity and Low Temperature Physics" as well as on "Magnetism and Spintronics". It is suitable for bachelor students in the 5th semester or higher and for master students.
