Ultracold bosons in the vicinity of a narrow resonance: shallow dimer and recombination
arXiv:1109.3002 · doi:10.1103/PhysRevA.84.062712
Abstract
The different resonant regimes that can be achieved by using a magnetic Feshbach resonance are analyzed with a separable two-channel model. Emphasis is put on the case of narrow resonances in a region of intermediate detuning where a shallow dimer exists and an approximate law including the background scattering length for the three-body recombination rate is derived.
