Charge and spin current statistics of the open Hubbard model with weak coupling to the environmentBuča, Berislav (Avtor) Prosen, Tomaž (Avtor) quantum mechanicsstatistical physicsopen systemsBased on generalization and extension of our previous work [Phys. Rev. Lett. 112, 067201 (2014)] to multiple independent Markovian baths we will compute the charge and spin current statistics of the open Hubbard model with weak system-bath coupling up to next-to-leading order in the coupling parameter. Only the next-to-leading and higher orders depend on the Hubbard interaction parameter. The physical results are related to those for the XXZ model in the analogous setup implying a certain universality, which potentially holds in this class of nonequilibrium models.American Physical Society20172017-07-27 13:00:45Neznano94328UDK: 536.9ISSN pri članku: 2470-0045DOI: 10.1103/PhysRevE.95.052141COBISS_ID: 3106404OceCobissID: 2048366611slAmerican Physical Society
