Pseudogap regime of a two-dimensional uniform Fermi gas
Morio Matsumoto, Ryo Hanai, Daisuke Inotani +1
We investigate pseudogap phenomena in a two-dimensional Fermi gas. Including pairing fluctuations within a self-consistent -matrix approximation, we determine the pseudogap temp…
Superfluid Fermi atomic gas as a quantum simulator for the study of neutron-star equation of state
Pieter van Wyk, Hiroyuki Tajima, Daisuke Inotani +2
We theoretically propose an idea to use an ultracold Fermi gas as a quantum simulator for the study of the neutron-star equation of state (EoS) in the low-density region. Our idea…
Closed-channel contribution in the BCS-BEC crossover regime of an ultracold Fermi gas with an orbital Feshbach resonance
Soumita Mondal, Daisuke Inotani, Yoji Ohashi
We theoretically investigate strong-coupling properties of an ultracold Fermi gas with an orbital Feshbach resonance (OFR). Including tunable pairing interaction associated with an…
Normal-state Properties of a Unitary Bose-Fermi Mixture: A Combined Strong-coupling Approach with Universal Thermodynamics
Digvijay Kharga, Hiroyuki Tajima, Pieter van Wyk +2
We theoretically investigate normal-state properties of a unitary Bose-Fermi mixture. Including strong hetero-pairing fluctuations, we evaluate the Bose and Fermi chemical potentia…
Spin susceptibility and effects of a harmonic trap in the BCS-BEC crossover regime of an ultracold Fermi gas
Hiroyuki Tajima, Ryo Hanai, Yoji Ohashi
We theoretically investigate magnetic properties of a trapped ultracold Fermi gas. Including pairing fluctuations within the framework of an extended -matrix approximation (ETMA…
Two-dimensional Schrödinger symmetry and three-dimensional breathers and Kelvin-ripple complexes as quasi-massive-Nambu-Goldstone modes
Daisuke A. Takahashi, Keisuke Ohashi, Toshiaki Fujimori +1
Bose-Einstein condensates (BECs) confined in a two-dimensional (2D) harmonic trap are known to possess a hidden 2D Schrödinger symmetry, that is, the Schrödinger symmetry modified…
Single-particle Excitations and Effects of Hetero-pairing Fluctuations in a Bose-Fermi Mixture with a Feshbach Resonance
Digvijay Kharga, Daisuke Inotani, Ryo Hanai +1
We theoretically investigate normal-state properties of a gas mixture of single-component bosons and fermions with a hetero-nuclear Feshbach resonance. Including strong hetero-pair…
Conformal symmetry of trapped Bose-Einstein condensates and massive Nambu-Goldstone modes
Keisuke Ohashi, Toshiaki Fujimori, Muneto Nitta
The Gross-Pitaevskii (GP) or nonlinear Schrödinger equation relevant to ultracold atomic gaseous Bose-Einstein condensates possess a modified Schrödinger symmetry in two spatial di…
Strong-coupling corrections to ground-state properties of a superfluid Fermi gas
Hiroyuki Tajima, Pieter van Wyk, Ryo Hanai +4
We theoretically present an economical and convenient way to study ground-state properties of a strongly interacting superfluid Fermi gas. Our strategy is that complicated strong-c…
Local Photoemission Spectra and Effects of Spatial Inhomogeneity in the BCS-BEC Crossover Regime of a Trapped Ultracold Fermi Gas
Miki Ota, Hiroyuki Tajima, Ryo Hanai +2
We theoretically investigate single particle excitations in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein-Condensation) crossover regime of an ultracold Fermi gas. Includi…
Specific Heat and Effects of Uniaxial Anisotropy of a -wave Pairing Interaction in a Strongly Interacting Ultracold Fermi Gas
Daisuke Inotani, Pieter van Wyk, Yoji Ohashi
We investigate the specific heat at constant volume and effects of uniaxial anisotropy of a -wave attractive interaction in the normal state of an ultracold Fermi gas. Wit…
Confinement of Half-quantized Vortices in Coherently Coupled Bose-Einstein Condensates: Simulating Quark Confinement in QCD
Minoru Eto, Muneto Nitta
We demonstrate that the confinement of half-quantized vortices (HQVs) in coherently coupled Bose-Einstein condensates (BECs) simulates certain aspects of the confinement in …
Appropriate conditions to realize a -wave superfluid state starting from a spin-orbit coupled -wave superfluid Fermi gas
T. Yamaguchi, D. Inotani, Y. Ohashi
We theoretically investigate a spin-orbit coupled -wave superfluid Fermi gas, to examine the time evolution of the system, after an -wave pairing interaction is replaced by a…
