Spin-orbit coupling profoundly changes the Fermi-surface topology of two-dimensional electron gases. We investigate the observable effects of these changes in collective responses of the underlying many-body systems. [read more]
  
Topological Insulators ENB Topologische Isulatoren
The International Doctorate Program is focusing on investigating the fundamental properties and potential applications of topological insulators. Topological insulators are a new state of matter with unique physical characteristics: their surfaces or edges are electrically conducting while the bulk of the material remains insulating. Additionally, the electron spin plays a decisive role for the conduction properties in these surfaces or edges, making topological insulators a very interesting subject for scientific studies. This also means that topological insulators are prime candidates for potential spintronic applications. [read more]
