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.
