Author(s): Robbe Ceulemans, Samuel E. Begg, Matthew J. Davis, and Michiel Wouters We show that a Bose-Hubbard model with local loss exhibits a first-order dark-state phase transition between a dark soliton and a uniform superfluid. Semiclassical simulations and stability analysis reveal that the soliton acts as a many-body dark state, whose suppressed fluctuations modify the tran… [Phys. Rev.
