Stability of fractional quantum Hall states in disordered photonic systems
New Journal of Physics
The possibility of realizing fractional quantum Hall liquids in photonic systems has attracted a great deal of interest of late. Unlike electronic systems, interactions in photonic systems must be engineered from non-linear elements and are thus subject to positional disorder. The stability of the topological liquid relies on repulsive interactions. In this paper we investigate the stability of fractional quantum Hall liquids to impurities which host attractive interactions. We find that fordoi:10.1088/1367-2630/aa89a5 fatcat:amqs3ei6mfgifhmu3xate7bddi
