Title: Universal few-body physics with atoms
Over the last few years, experiments with ultra-cold atoms have confirmed
the universality of few-particle physics when these particles interact with
a large scattering length. In particular, these experiments evidenced the
Efimov effect, a universal three-body binding mechanism originally
predicted 40 years ago in the context of nuclear physics. Although the
universality of few-particle properties was confirmed, small non-universal
deviations were also observed.
In this talk, I will present the Efimov effect, how it was observed
experimentally with atoms, and our theoretical analysis of non-universal
deviations found in the experiments.
