Bose-Einstein droplet in free space

Abstract

We show that a droplet of a Bose-Einstein condensate can be dynamically stabilized in free space by rapid oscillations of interatomic interactions between attractive and repulsive through, e.g., the Feshbach resonance. Energy dissipation, which is present in realistic situations, is found to play a crucial role to suppress dynamical instabilities inherent in nonlinear nonequilibrium systems.
