Reservoir engineering with localized dissipation: Dynamics and prethermalization

Abstract

This paper analyzes the dynamics of a large quantum lattice of non-interacting bosons when it is locally coupled to a reservoir of squeezed light. The authors find that the medium term evolution of the lattice shows ballistic behavior, with a quasi-stationary state on the inside of an expanding light-cone. In the long term, the system's approach to a final steady state is dictated by a dissipative spectrum that shows complex, non-monotonous dependence on the strength of the coupling to the reservoir.
