Pseudogap temperature and effects of a harmonic trap in the BCS-BEC crossover regime of an ultracold Fermi gas
Shunji Tsuchiya, Ryota Watanabe, Yoji Ohashi
We theoretically investigate excitation properties in the pseudogap regime of a trapped Fermi gas. Using a combined -matrix theory with the local density approximation, we calcu…
Superfluid/ferromagnet/superfluid-junction and -phase in a superfluid Fermi gas at finite temperatures
Takashi Kashimura, Shunji Tsuchiya, Yoji Ohashi
We investigate the stability of -phase in a polarized superfluid Fermi gas (, where is the number of atoms in the hyperfine state described by pse…
Inhomogeneous Pseudogap Phenomenon in the BCS-BEC Crossover Regime of a Trapped Superfluid Fermi Gas
Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi
We investigate pseudogap phenomena in the unitarity limit of a trapped superfluid Fermi gas. Including effect of strong pairing fluctuations within a -matrix approximation, as w…
-junction and spontaneous current state in a superfluid Fermi gas
Takashi Kashimura, Shunji Tsuchiya, Yoji Ohashi
We discuss an idea to realize a spontaneous current in a superfluid Fermi gas. When a polarized Fermi superfluid ($N_\up > N_\dwn$, where is the number of atoms in the hyperf…
Theory of Photoemission-type Experiment in the BCS-BEC Crossover Regime of a Superfluid Fermi Gas
Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi
We theoretically investigate the recent photoemission-type experiment on K Fermi gases done by JILA group. Including pairing fluctuations within a strong-coupling -matrix…
Spin imbalance effect on Larkin-Ovchinnikov-Fulde-Ferrel state
Ryosuke Yoshii, Shunji Tsuchiya, Giacomo Marmorini +1
We study spin imbalance effects on the Larkin-Ovchinikov-Fulde-Ferrel (LOFF) state relevant for superconductors under a strong magnetic field and spin polarized ultracold Fermi gas…
