Abstract: We investigate the attractive Hubbard model in infinite spatial dimensions atquarter filling. By combining dynamical mean-field theory with continuous-timequantum Monte Carlo simulations in the Nambu formalism, we directly deal withthe superfluid phase in the population imbalanced system. We discuss the lowenergy properties in the polarized superfluid state and the pseudogap behaviorin the vicinity of the critical temperature.
