Abstract
We study the stability of a zero temperature mixture of attractively
interacting degenerate bosons and spin-polarized fermions in the absence
of confinement. We demonstrate that higher order corrections to the
standard mean-field energy can lead to a formation of Bose-Fermi liquid
droplets – self-bound systems in three-dimensional space. The stability
analysis of the homogeneous case is supported by numerical simulations
of finite systems by explicit inclusion of surface effects. We discuss
the experimental feasibility of formation of quantum droplets and
indicate the main obstacle – inelastic three-body collisions.
