Uniform spin susceptibility and spin-gap phenomenon in the BCS-BEC crossover regime of an ultracold Fermi gas
H. Tajima, T. Kashimura, R. Hanai +2
We investigate the uniform spin susceptibility in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover regime of an ultracold Fermi gas. Inclu…
Pseudogap phenomenon and effects of population imbalance in the normal state of a unitary Fermi gas
Takashi Kashimura, Ryota Watanabe, Yoji Ohashi
We investigate strong-coupling corrections to single-particle excitations in the normal state of a spin-polarized unitary Fermi gas. Within the framework of an extended T-matrix ap…
Excitation properties and effects of mass imbalance in the BCS-BEC crossover regime of an ultracold Fermi gas
Ryo Hanai, Takashi Kashimura, Ryota Watanabe +2
We investigate single-particle properties of a mass-imbalanced Fermi gas in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover region. In the presence o…
Low-dimensional pairing fluctuations and pseudogapped photoemission spectrum in a trapped two-dimensional Fermi gas
Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi
We investigate strong-coupling properties of a trapped two-dimensional normal Fermi gas. Within the framework of a combined -matrix theory with the local density approximation,…
Spin Susceptibility and Strong Coupling Effects in an Ultracold Fermi Gas
Hiroyuki Tajima, Ryo Hanai, Ryota Watanabe +1
We investigate magnetic properties and strong coupling corrections in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover regime of an ultracold Fermi ga…
