About me

I am a postdoc in the group of Emil Bergholtz working on fractional Chern insulators in moiré structures. In these materials, topology and strong correlations come together and give rise to the fractional quantum anomalous Hall effect without the need for an external magnetic field.
Before coming to Stockholm University, I did my PhD at Chalmers University of Technology funded via an Excellence PhD position. There I worked on modelling the physics of charge (electron-hole) complexes in atomically thin semiconductors. My work was awarded with the best thesis award at the Department of Physics.

Sculptured Topological Heterostructures

In this theoretical project, we intend to investigate what happens when we assemble exotic topological components. More specifically, we want to investigate four types of "sculptured topological heterostructures" as briefly described below.
