SPINOR FERMI GASES

At first, we consider an ideal gas of harmonically trapped fermions with total angular momentum F = 3/2 and calculate, e.g., the temperature dependence of the heat capacity for a fixed magnetization. Afterwards, the isotropic short-range contact-interaction is treated perturbatively and its influence on the ground-state energy is worked out. Such spinor Fermi gases are important, for example, in the context of a ⁵²Cr-⁵³Cr boson-fermion mixture.¹
