Stability of the Superfluid State in Three-Component Fermionic Optical Lattice Systems

Quantum Gases 2015-06-18 v1

Abstract

Three-component fermionic optical lattice systems are investigated in dynamical mean-field theory for the Hubbard model. Solving the effective impurity model by means of continuous-time quantum Monte Carlo simulations in the Nambu formalism, we find that the ss-wave superfluid state proposed recently is indeed stabilized in the repulsively interacting case and appears along the first-order phase boundary between the metallic and paired Mott states in the paramagnetic system. The BCS-BEC crossover in the three-component fermionic system is also addressed.
