Geometry of system-bath coupling and gauge fields in bosonic ladders: manipulating currents and driving phase transitions
Quantum systems in contact with an environment display a rich physics emerging from the interplay between dissipative and Hamiltonian terms. We consider a dissipative boundary driven ladder in presence of a gauge field. The dissipation stimulates currents while the gauge field tends to steer the flow. We show that depending on the geometry of coupling to the baths and of the strength of the gauge field, non-equilibrium phase transitions emerge strongly modifying the currents both in magnitude and spatial distribution.
