The quasimomentum distribution, ground-state energy, and generalized velocities are obtained as functions of the interaction strength both for polarized and nonpolarized fermions. We do not observe any demixing instability of the system for repulsive interactions.Keywords: Electromagnetic wave polarization; Electron energy levels; Elementary particle sources; Functions; Ground state; Boson-fermion gas; Ground-state energy; Nonpolarized fermions; Quasimomentum distribution; Fermions200510.1103/PhysRevA.72.0616032015-12-11
