Dimensionality of a strongly interacting 2D-3D Fermi-Fermi mixture from the perspective of superfluid instability and excitation properties
Haruka Takeda, Saki Hirai, Shumpei Iwasaki +1
We theoretically investigate strong-coupling properties of an attractively interacting Fermi atomic gas, where the Cooper-pair formation occurs between atoms belonging to different…
Superfluid density and condensate fraction in the BCS-BEC crossover regime at finite temperatures
N. Fukushima, Y. Ohashi, E. Taylor +1
The superfluid density is a fundamental quantity describing the response to a rotation as well as in two-fluid collisional hydrodynamics. We present extensive calculations of the s…
Itinerant-localized dual character of a strongly-correlated superfluid Bose gas in an optical lattice
Y. Ohashi, M. Kitaura, H. Matsumoto
We investigate a strongly-correlated Bose gas in an optical lattice. Extending the standard-basis operator method developed by Haley and Erdos to a boson Hubbard model, we calculat…
Effective interaction between molecules in the BEC regime of a superfluid Fermi gas
Y. Ohashi
We investigate the effective interaction between Cooper-pair molecules in the st rong-coupling BEC regime of a superfluid Fermi gas with a Feshbach resonance. Our work uses a path…
Comment on "Novel Superfluidity in a Trapped Gas of Fermi Atoms with Repulsive Interaction Loaded on an Optical Lattice"
M. Rigol, S. R. Manmana, A. Muramatsu +3
In a recent letter Machida et al. [Phys. Rev. Lett. 93, 200402 (2004)] concluded that in a trapped gas of fermions with repulsive interactions a superfluid phase appears around the…
Fermi excitations in a trapped atomic Fermi gas with a molecular Bose condensate
Y. Ohashi, A. Griffin
We discuss the effect of a molecular Bose condensate on the energy of Fermi excitations in a trapped two-component atomic Fermi gas. The single-particle Green's functions can be ap…
