Hall viscosity and putative quantum Hall states without positive-definite K-matrix
Emanuele Di Salvo, Dirk Schuricht, Joost K. Slingerland +1
We investigate putative quantum Hall effect states, labeled by their K-matrix equal to (1 1 3), by defining them on the torus and computing their Hall viscosity. Such states have b…

Haldane model on the SierpiÅski gasket
Zebedeus Osseweijer, Lumen Eek, Anouar Moustaj +2
We investigate the topological phases of the Haldane model on the SierpiÅski gasket. As a consequence of the fractal geometry, multiple fractal gaps arise. Additionally, a flat ba…
