Optimal transport and von Neumann entropy in an Heisenberg XXZ chain out of equilibrium
Mario Salerno, Vladislav Popkov
In this paper we investigate the spin currents and the von Neumann entropy (VNE) of an Heisenberg XXZ chain in contact with twisted XY-boundary magnetic reservoirs by means of the…
Anomalous currents in driven XXZ chain with boundary twisting at weak coupling or weak driving
Vladislav Popkov, Mario Salerno
The spin 1/2 XXZ chain driven out of equilibrium by coupling with boundary reservoirs targeting perpendicular spin orientations in XY plane, is investigated. The existence of an an…
Boundary-driven phase transitions in open two-species driven systems with an umbilic point
V. Popkov
Different phases in open driven systems are governed by either shocks or rarefaction waves. A presence of an isolated umbilic point in bidirectional systems of interacting particle…
Unusual shock wave in two-species driven systems with an umbilic point
Vladislav Popkov, Gunter M. Schütz
Using dynamical Monte-Carlo simulations we observe the occurrence of an unexpected shock wave in driven diffusive systems with two conserved species of particles. This U-shock is m…
Singular response to a dopant of an evaporating crystal surface
Vladislav Popkov, Paolo Politi
Moving crystal surfaces can undergo step-bunching instabilities, when subject to an electric current. We show analytically that an infinitesimal quantity of a dopant may invert the…
