Transition from Band insulator to Bose-Einstein Condensate superfluid and Mott State of Cold Fermi Gases with Multiband Effects in Optical Lattices
Ryota Watanabe, Masatoshi Imada
We study two models realized by two-component Fermi gases loaded in optical lattices. We clarify that multi-band effects inevitably caused by the optical lattices generate a rich s…

Single-particle properties and pseudogap effects in the BCS-BEC crossover regime of an ultracold Fermi gas above Tc
Shunji Tsuchiya, Ryota Watanabe, Yoji Ohashi
We investigate strong-coupling effects on normal state properties of an ultracold Fermi gas. Within the framework of -matrix approximation in terms of pairing fluctuations, we c…

Pseudogap in fermionic density of states in the BCS-BEC crossover of atomic Fermi gases
S. Tsuchiya, R. Watanabe, Y. Ohashi
We study pseudogap behaviors of ultracold Fermi gases in the BCS-BEC crossover region. We calculate the density of states (DOS), as well as the single-particle spectral weight, abo…
