Advanced Seminar WS 2018/19

"Control and Dynamics of Quantum Materials"

Mo. 14:00-15:00 h in the Seminar Room 202 of the II. Physikalisches Institut, University of Cologne.

In this Advanced Seminar we shall introduce and discuss so-called quantum materials, whose fundamental properties and functionalities arise from a quantum mechanical interplay of their constituents. At the forefront of this field of research are new materials, in which relativistic spin-orbit effects and non-trivial topologies cause new quantum many-body states and materials with strong electronic correlations, which exhibit a wealth of non-trivial quantum ordering phenomena including superconductivity, magnetism, and other exotic orders.In this research field new discoveries and new opportunities for controlling materials properties can be expected and the Deutsche Forschungsgemeinschaft is actually funding the Collaborative Research Center 1238, whose experimental research is located at the II. Physikalisches Institut. In this Advanced Seminar we plan to discuss some of the major research activities in this field with sepcial emphasis on the experimental investigations of various material classes of interest. The seminar talks shall focus on the presentation of the experimental signatures of, e.g., new types of order and/or anomalous excitations. In addition, some specific experimental techniques should be explained and an overview about the underlying theoretical concepts should be given.
