Specific heat and effects of pairing fluctuations in the BCS-BEC crossover regime of an ultracold Fermi gas

Pieter van Wyk, Hiroyuki Tajima, Ryo Hanai +1

We investigate the specific heat at constant volume in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover regime of an ultracold Fermi gas above t…

Spin susceptibility and effects of inhomogeneous strong pairing fluctuations in a trapped ultracold Fermi gas

Hiroyuki Tajima, Ryo Hanai, Yoji Ohashi

We theoretically investigate magnetic properties of a unitary Fermi gas in a harmonic trap. Including strong pairing fluctuations within the framework of an extended -matrix app…

Strong Coupling Effects on the Specific Heat of an Ultracold Fermi Gas in the Unitarity Limit

Pieter van Wyk, Hiroyuki Tajima, Ryo Hanai +1

We investigate strong-coupling corrections to the specific heat in the normal state of an ultracold Fermi gas in the BCS-BEC crossover region. A recent experiment on a Li…

Non-equilibrium properties of a pumped-decaying Bose-condensed electron-hole gas in the BCS-BEC crossover region

Ryo Hanai, Peter B. Littlewood, Yoji Ohashi

We theoretically investigate a Bose-condensed exciton gas out of equilibrium. Within the framework of the combined BCS-Leggett strong-coupling theory with the non-equilibrium Keldy…

Triplet pair amplitude in a trapped -wave superfluid Fermi gas with broken spin rotation symmetry

Yuki Endo, Daisuke Inotani, Ryo Hanai +1

We investigate the possibility that the broken spatial inversion symmetry by a trap potential induces a spin-triplet Cooper-pair amplitude in an -wave superfluid Fermi gas. Bein…
