Raul Perea CausinPostdoktor

Om mig

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.

Skulpterade topologiska heterostrukturer

I detta teoretiska projekt ämnar vi undersöka vad som händer när vi istället sätter ihop exotiska topologiska komponenter. Mer specifikt vill vi undersöka fyra typer av “skulpterade topologiska heterostrukturer” som beskrivs kortfattat nedan.
