Ultra cold atomic gases Bose-Fermi mixture

This study, conducted by Takayuki Watanabe from Tokyo Metropolitan University along with T. Suzuki and P. Schuck, investigates the stability of Bose-Fermi mixtures in ultra-cold atomic gases. Key topics include fermionic pairs, dispersion relations, and occupation numbers. The research applies the T-matrix approach employing both non-self-consistent methods and a perspective for future self-consistent treatment. The findings highlight the quantum phase behavior of these mixtures and analyze pressure as a function of inverse scattering length, revealing collective modes reminiscent of Bose-Fermi pairs.
