According to their threshold behavior, we find Feshbach resonances can be classified into two types.doi:10.48550/arXiv.cond-mat/0506313Cheng ChinPhysicsC. Chin, A simple model of Feshbach molecules, cond-mat/0506313 (2005).Cheng Chin. A simple model of Feshbach molecules. http://arxiv.org...
Here we report a very pronounced and narrow (25 mG) Feshbach resonance in collisions between two triplet ground-state NaLi molecules. This molecular Feshbach resonance has two special characteristics. First, the collisional loss rate is enhanced by more than two orders of magnitude above the ...
We show that the photoassociation (PA) rate of ultracold diatomic molecules in the vicinity of a Feshbach resonance could be used to probe variations of the electron-to-proton mass ratio β=me/mp, a quantity related to other fundamental constants via the ΛQCD scale. The PA rate exhibits ...
The centre of mass of the cloud then impacts on the detector after a [Math Processing Error]τ=417 ms time of flight following the trap switch-off. Investigations of the quantum depletion in He[Math Processing Error]∗ are challenging because the absence of a known Feshbach resonance ...

Varying the temperature can hence provide some insight into to the energy dependence of the resonance18,19,20, but by its nature this method is associated with thermal broadening. Measurements in the energy domain have also been achieved by dissociating Feshbach molecules through a fast and non-...
