Key aspects of activity
- Thore likes physics 'with a twist'. He is particulary interested in topologically robust phenomena in spin chains, anyons, and Majorana fermions with a possible application to quantum computing. He also works on the Kondo effect for topological electronic phases with special focus on the Kondo cloud as well magnetic and superconducting materials at the edge states of topological insulators and hybrid systems consisting of a trivial insulator and a topological insulator.

Key aspects of activity
- Martin's heart beats bosonization. As expert for anyons in ERC Starting Grant project QUANTWIST, Martin bosonizes and applies other field theoretical tools to low-dimensional theories and extracts the quasi-particles' characteristic properties.
