In recent years, we have worked very actively on topological materials
, whose band structures are characterized mathematically by topological invariants. These materials display interesting surface phenomena and can host emergent quantum particles like Majorana fermions. In particular, we have worked on the effect of electronic correlations and spin-orbit coupling on such materials.
A recurring theme have been quantum transport phenomena
in various mesoscopic settings. In this domain, our group has experience with the description of charge or heat transport in systems such as nanowires, topological insulators, quantum dots, and graphene. Recently, we have explored how transport is affected by electronic correlations in nanowires and graphene.
In quantum mechanics, the description of many-particle systems in the presence of interactions is a hard problem which calls for highly specialized techniques. Our group performs mainly analytical calculations on simplified model systems using methods from quantum field theory. In addition to this, we often test these model predictions against numerical simulations.
