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…

Reduced density matrix and entanglement entropy of permutationally invariant quantum many-body systems
V. Popkov, Mario Salerno
In this paper we discuss the properties of the reduced density matrix of quantum many body systems with permutational symmetry and present basic quantification of the entanglement…

Hydrodynamic limit of multi-chain driven diffusive models
V. Popkov, M. Salerno
A new class of models, generalizing Asymmetric Exclusion Process for many parallel interacting channels, is proposed. We couple the models with boundary reservoirs, study boundary-…
