Description
In this talk, I will discuss general properties of few-body collisions and their influence
on ultracold quantum gases in the regime where interatomic interactions are strongly
affected by a Feshbach resonance. Since the early days of the achievement of Bose-Einstein
condensation, it has been recognized that few-body processes are of crucial importance in
determining the stability of condensates. Nevertheless, ultracold gases also offer an outstanding
opportunity to explore one of the most counterintuitive quantum phenomena that manifest
in a "simple" few-particle system: the Efimov effect. In fact, the first strong experimental
evidence of Efimov physics was recently found in ultracold quantum gases as a giant loss of atoms
causing the gas to become highly unstable.
Nowadays, we know that Efimov physics affects three-body processes in experiments on
ultracold quantum gases, and it now serves as a "guide" in the difficult task of achieving
atomic and molecular stability. In this talk, I will outline some of my recent
work on Efimov physics and also discuss some of its implications for the many-body
behavior of ultracold quantum gases.
