摘要: We study, both analytically and numerically, the Boltzmann transport equation for Hubbard chain with nearest-neighbor hopping spatially homogeneous initial condition. The time-dependent Wigner function is matrix-valued because of spin. H theorem holds. integrable, which, on kinetic level, reflected by infinitely many additional conservation laws linked to fact that there are also nonthermal stationary states. characterize all solutions. Numerically, we observe an exponentially fast convergence stationarity investigate rate in dependence conditions.
