Steady-state phases and tunneling-induced instabilities in the driven-dissipative Bose-Hubbard model

Alexandre Le Boité, Giuliano Orso, Cristiano Ciuti

We determine the steady-state phases of a driven-dissipative Bose-Hubbard model, describing, e.g., an array of coherently pumped nonlinear cavities with a finite photon lifetime. W…
