Short presentation

My passion is to construct pictures of physical phenomena by means of the mathematical tools at my disposal. The theoretical comprehension is partly built on mathematical methods but also includes insights and descriptions that goes beyond the mathematical interpretation. In particular, I am interested in magnetic and spin based phenomena out of equilibrium, where vibrations, external forces, and time plays part for the physics.

Chirality and Quantum Spin – a Critical Assessment

Research

Research Interests

Non-equilibrium condensed matter physics with special attention to the modeling of nanostructures systems and local probing techniques. Particular focus is directed on impurity scattering in two-dimensional systems, where the impurities possess bosonic (vibrational, spin, ...) degrees of freedom which give rise to inelastic scattering processes. Interactions between local defects adsorbed onto surface of modern materials e.g. superconductors, graphene, topological insulators, strongly spin-orbit coupled surfaces, and hidden order materials. At the moment my devotion is set to chiral induced spin selectivity, where spatial and spin degrees of freedom cooperate with electron correlations and vibrations to generate a macroscopically measurable spin asymmetry in the charge current.
