“气态液滴”--一种在自由空间中自行凝聚的稳定气体--被证明是由玻色-爱因斯坦凝聚体产生的。通过吸引和排斥之间的原子间相互作用的快速振荡来抑制液滴的塌陷和膨胀，费什巴赫共振能量耗散，这是目前在现实的情况下，被发现在抑制动力学不稳定，不稳定的液滴中发挥了至关重要的作用。
A 'gaseous droplet' - a stable gas that coheres by itself in free space - is shown to be produced with a Bose-Einstein condensate. Collapse and expansion of the droplet are suppressed by rapid oscillations of the interatomic interaction 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 in suppressing dynamical instabilities that destabilize the droplet.
