Mixing-demixing in a trapped degenerate fermion-fermion mixture
arXiv:cond-mat/0607119 · doi:10.1103/PhysRevA.73.043619
Abstract
We use a time-dependent dynamical mean-field-hydrodynamic model to study mixing-demixing in a degenerate fermion-fermion mixture (DFFM). It is demonstrated that with the increase of interspecies repulsion and/or trapping frequencies, a mixed state of DFFM could turn into a fully demixed state in both three-dimensional spherically-symmetric as well as quasi-one-dimensional configurations. Such a demixed state of a DFFM could be experimentally realized by varying an external magnetic field near a fermion-fermion Feshbach resonance, which will result in an increase of interspecies fermion-fermion repulsion, and/or by increasing the external trap frequencies.
