Alternation of sign of magnetization current in driven XXZ chains with twisted XY boundary gradients
V. Popkov
We investigate an open XXZ spin 1/2 chain driven out of equilibrium by coupling with boundary reservoirs targeting different spin orientations in XY plane. Symmetries of the model…

Manipulating energy and spin currents in nonequilibrium systems of interacting qubits
Vladislav Popkov, Roberto Livi
We consider generic interacting chain of qubits, which are coupled at the edges to baths of fixed polarizations. We can determine the nonequilibrium steady states, described by the…
