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 s-wave superfluid state proposed recently is indeed stabilized in the repulsively interacting case and appears along a first-order phase boundary between metallic and paired Mott states in the paramagnetic system. The BCS-BEC (Bose-Einstein condensation) crossover in the three-component fermionic system is also addressed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
