Query: Quantum Bose-Fermi droplets   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.
