Recent studies using the adiabatic hyperspherical representation have helped to provide an understanding of the universal three-body parameter for both homonuclear and heteronuclear systems characterized by van der Waals plus short-range interactions. This talk will discuss the current state of theoretical analyses of this important aspect of the universal Efimov effect, and what has been...

In my talk I shall overview our experimental studies of the three-body recombination process in a gas of ultracold lithium atoms. In the regime of resonant interatomic interactions we identify the characteristic features of Efimov trimers [1]. In the opposite regime of vanishingly weak interactions, where no universal bound states are expected, we discover a surprisingly simple behavior. We...

The three-body recombination rates in cold atomic gases typically exhibit certain universal features --- often referred to as Efimov physics --- which can be described within a model-independent theory using only very few of the low-energy parameters of the inter-atomic interactions.
In this contribution we specifically consider recombination into expressly non-universal deep dimers. Even...
