Quantum materials are materials whose properties are decisively determined by quantum mechanics. As a part of condensed matter physics, this class will review some of the most famous quantum materials such as heavy fermion systems, high-temperature superconductors and topological materials. We will take a look at their physical properties, including phenomena like superconductivity, Kondo effect, exotic magnetic orders and charge-density waves. In addition to these important concepts of condensed matter physics, we will also get to know a range of experimental techniques that were used to find out about them. Thus, we will get insight into the process of understanding a new material in condensed matter physics and the critical analysis of experimental results and their interpretations.

Superconductivity is a phenomenon that is in the center of current research and still holds many surprises – even more than 100 years after its discovery. Open questions are, for example: Which materials may become superconducting? Why is a material a superconductor? How can we improve superconducting properties for applications? In this seminar we will approach the research field of superconductivity from different perspectives. Besides fundamental properties and applications, theory and experiment, possible topics may also include the history of superconductivity research or the properties of newly discovered superconducting materials.

First meeting to discuss formalities: 15.4., 4pm:
