Title: Quasi-viscous effects in open quantum systems
Abstract: In quantum transport problems, thermal environment plays an important role. We
demonstrate that additionally to suppressing quantum transport due to dephasing, the
environment is able to induce new dynamic effects absent in an isolated system. In
particular, we show that non-interacting particles in presence of stochastic environment
may exhibit formation of vortices and Poiseuille flow, the effects similar to commonly
considered signatures of hydrodynamic behavior. We provide a detailed analysis of the
phenomenon and derive the equations for quasi-viscous flow. The environmentally induced
quantum quasi-viscosity suggests new possible transport regimes accessible in solid-state
devices, cold atomic systems, and photonic quantum simulators.
