DOI: 10.1088/1367-2630/ad748f
Abstract: We present a superquantization rule which indicates the possible robust stationary states of a generic driven-dissipative quantum system. Multistability in a driven cavity mode interacting with a qudit is revealed hence within a simple intuitive… read more here.
