Kort presentation

Min stora passion i mitt arbete är att konstruera bilder av fysikaliska fenomen med hjälp av de matematiska verktygen som finns tillhanda. Den teoretiska kunskapsbildningen grundar sig delvis på matematiska metoder men rymmer insikter och beskrivningar som går utanför den matematiska tolkningen. Speciellt är jag intresserad av magnetiska och spinnbaserade fenomen bortom jämvikt, där vibrationer, yttre krafter och tiden spelar roll för fysiken.

Chirality and Quantum Spin – a Critical Assessment


Denna text finns inte på svenska, därför visas den engelska versionen.

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.
