Analytic solution of the domain-wall nonequilibrium stationary state
We consider the out-of-equilibrium dynamics generated by joining two domains with arbitrary opposite magnetizations. We study the stationary state which emerges by the unitary evolution via the spin-1/2 XXZ Hamiltonian, in the gapless regime, where the system develops a stationary spin current. Usin...
