Polarized Superfluidity in the Imbalanced Attractive Hubbard Model
Polarized Superfluidity in the Imbalanced Attractive Hubbard Model
We investigate the attractive Hubbard model in infinite spatial dimensions by means of dynamical mean-field theory. Using a continuous-time Monte Carlo algorithm in the Nambu formalism as an impurity solver, we directly deal with the superfluid phase in the population imbalanced system. By calculating the superfluid order parameter, the magnetization, …
