Three-Body Recombination in Atoms with Large Scattering Length Original Research Article

Atoms with a large scattering a have universal propertes that are insensitive to short-distance details. The universal predictions for the 3-body recombination rate are known at threshold, where they depend on a and a 3-body parameter, and in the high energy scaling limit, where they depend only on the collision energy. The universal results at threshold are particularly remarkable, exhibiting resonance peaks and interference minima. They played a significant role in recent experimental evidence for Efimov physics.
