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 ${\kappa }_T$ in the normal state of an ultracold Fermi gas. Including pairing fluctuations, as well as preformed-pair formati…
