Exact results for the 1D interacting mixed Bose-Fermi gas
arXiv:cond-mat/0506478 · doi:10.1103/PhysRevA.72.061603
Abstract
The exact solution of the 1D interacting mixed Bose-Fermi gas is used to calculate ground-state properties both for finite systems and in the thermodynamic limit. The quasimomentum distribution, ground-state energy and generalized velocities are obtained as functions of the interaction strength both for polarized and non-polarized fermions. We do not observe any demixing instability of the system for repulsive interactions.
