Superfluid gap formation in a fermionic optical lattice with spin imbalanced populations (1007.3307v1)
Published 19 Jul 2010 in cond-mat.quant-gas
Abstract: We investigate the attractive Hubbard model in infinite spatial dimensions at quarter filling. By combining dynamical mean-field theory with continuous-time quantum Monte Carlo simulations in the Nambu formalism, we directly deal with the superfluid phase in the population imbalanced system. We discuss the low energy properties in the polarized superfluid state and the pseudogap behavior in the vicinity of the critical temperature.
