Droplets of bosons at a narrow resonance
We consider bosons interacting through a narrow ๐ -wave resonance. Such a resonance is characterized by an infinite scattering length and a large and negative effective range ๐0. We argue that any number ๐โฅ3 of bosons can form a self-bound cluster with the binding energy per particle increasing as ๐2...

| Summary: | We consider bosons interacting through a narrow ๐ -wave resonance. Such a resonance is characterized by an infinite scattering length and a large and negative effective range ๐0. We argue that any number ๐โฅ3 of bosons can form a self-bound cluster with the binding energy per particle increasing as ๐2 for 1โช๐โช(โ๐0/๐bg)1/2, where ๐bg is the background scattering length (between atoms and molecules). In the opposite limit ๐โซ(โ๐0/๐bg)1/2, bosons form droplets with binding energy per particle saturating to a constant value independent of the particle number. The stability of clusters and droplets when the interaction is detuned from the resonance is also studied. |
