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 Roček, for why the existence of fractional charge necessarily implies fractional statistics. In doing so, we resolve a cont…
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 ($…
Mixed higher-order topology and nodal and nodeless flat band topological phases in a superconducting multiorbital model
Rodrigo Arouca, Tanay Nag, Annica M. Black-Schaffer
We investigate the topological phases that appear in an orbital version of the Benalcazar-Bernevig-Hughes (BBH) model in the presence of conventional spin-singlet -wave supercon…
