Summary
A parity-time (PT-) symmetric structure call be implemented by coupling an active element to a lossy one. Any stationary process in such a bicentric configuration must he sustained by the energy flux directed from active region to the domain of dissipation. We study these energy currents arising in PT-symmetric systems and examine the dependence of the flux strength on the gain-and-loss amplitude. First, we address stationary spatially localized modes and demonstrate the existence of the anomalous regime, where the increase of the gain-and-loss rate produces the drop of the flux through the gain-loss interface. Additionally, we consider spatially extended nonlinear patterns in the form of PT-symmetric through-flows. Some nonlinear solutions are found in exact analytical form.
