Coexistence of superfluid gap and pseudogap in the BCS-BEC crossover regime of a trapped Fermi gas below
Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi
We investigate strong pairing fluctuations and effects of a harmonic trap in the superfluid phase of an ultracold Fermi gas. Including amplitude and phase fluctuations of the inhom…
Spin susceptibility and fluctuation corrections in the BCS-BEC crossover regime of an ultracold Fermi gas
Takashi Kashimura, Ryota Watanabe, Yoji Ohashi
We investigate magnetic properties and effects of pairing fluctuations in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover regime of an ultracold Ferm…
Superfluid phase transition and strong-coupling effects in an ultracold Fermi gas with mass imbalance
Ryo Hanai, Takashi Kashimura, Ryota Watanabe +2
We investigate the superfluid phase transition and effects of mass imbalance in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover regime of an cold Fer…
Magnetic properties and strong-coupling corrections in an ultracold Fermi gas with population imbalance
Takashi Kashimura, Ryota Watanabe, Yoji Ohashi
We investigate magnetic properties of an ultracold Fermi gas with population imbalance. In the presence of population imbalance, the strong-coupling theory developed by Nozieres an…
Two-dimensional pseudogap effects of an ultracold Fermi gas in the BCS-BEC crossover region
Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi
We investigate pseudogap phenomena originating from pairing fluctuations in the BCS-BEC crossover regime of a two-dimensional Fermi gas in a harmonic trap. Including pairing fluctu…
Pseudogap phenomenon in an ultracold Fermi gas with a p-wave pairing interaction
D. Inotani, R. Watanabe, M. Sigrist +1
We investigate single-particle properties of a one-component Fermi gas with a tunable p-wave interaction. Including pairing fluctuations associated with this anisotropic interactio…
