Topology and energy dependence of Majorana bound states in a photonic cavity
Aksel KobiaÅka, Arnob Kumar Ghosh, Rodrigo Arouca +1
Light-matter interaction plays a crucial role in modifying the properties of quantum materials. In this work, we investigate the effect of cavity induced photon fields on a topolog…

On the relation between fractional charge and statistics
T. H. Hansson, Rodrigo Arouca, Thomas Klein Kvorning
We revisit an argument, originally given by Kivelson and RoÄek, for why the existence of fractional charge necessarily implies fractional statistics. In doing so, we resolve a con…

Local and energy-resolved topological invariants for Floquet systems
Arnob Kumar Ghosh, Rodrigo Arouca, Annica M. Black-Schaffer
Periodically driven systems offer a perfect breeding ground for out-of-equilibrium engineering of topological boundary states at zero energy (-mode), as well as finite energy ($…
