Thermodynamic geometry of ideal quantum gases: a general framework and a geometric picture of BEC-enhanced heat engines
Joshua Eglinton, Tuomas Pyharanta, Keiji Saito +1
Thermodynamic geometry provides a physically transparent framework to describe thermodynamic processes in meso- and micro-scale systems that are driven by slow variations of extern…
Non-Hermitian topological Fermi superfluid near the -wave unitary limit
Hiroyuki Tajima, Yuta Sekino, Daisuke Inotani +3
We theoretically discuss the non-Hermitian superfluid phase transition in one-dimensional two-component Fermi gases near the -wave Feshbach resonance accompanied by the two-body…
Dark quantum droplets and solitary waves in beyond-mean-field Bose-Einstein condensate mixtures
Matthew Edmonds
Quantum liquid-like states of matter have been realized in an ongoing series of experiments with ultracold Bose gases. Using a combination of analytical and numerical methods we id…
Feasibility of a Fulde-Ferrell-Larkin-Ovchinnikov superfluid Fermi atomic gas
Taira Kawamura, Yoji Ohashi
We theoretically explore a promising route to achieve the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state in a spin-imbalanced ultracold Fermi gas. In the current stage of cold atom…
Isothermal compressibility and effects of multi-body molecular interactions in a strongly interacting ultracold Fermi gas
Daichi Kagamihara, Ryohei Sato, Koki Manabe +2
We theoretically investigate the isothermal compressibility in the normal state of an ultracold Fermi gas. Including pairing fluctuations, as well as preformed-pair formati…
