We study the time evolution of an half-field Hubbard layer coupled to a magnon bath after a quench of the Hubbard interaction. Qualitatively different regimes, regarding the asymptotic long time dynamics, are identified and characterized within the mean-field approximation. In the absence of the bath, the dynamics of the closed system is similar to that of a quenched BCS condensate. Though the presence of the bath introduces an additional relaxation mechanism, our numerical results and analytical arguments show that equilibration with the bath is not necessarily attained. % at least within the mean-field approximation. Instead, non-equilibrium states, similar to the ones observed in the closed system, can emerge at long times as a consequence of the competition between intrinsic relaxation mechanism, such as Landau damping, and the bath-induced dissipation.
