# Out-of-equilibrium steady states of a locally driven lossy qubit array

@article{Dutta2021OutofequilibriumSS, title={Out-of-equilibrium steady states of a locally driven lossy qubit array}, author={Shovan Dutta and N. Cooper}, journal={Physical Review Research}, year={2021} }

We find a rich variety of counterintuitive features in the steady states of a qubit array coupled to a dissipative source and sink at two arbitrary sites, using a master equation approach. We show there are setups where increasing the pump and loss rates establishes long-range coherence. At sufficiently strong dissipation, the source or sink effectively generates correlation between its neighboring sites, leading to a striking density-wave order for a class of "resonant" geometries. This effect…
