Description
Efimov states form in a three-body system when the pair-wide interactions are resonantly enhanced. Predicted by Vitaly Efimov in 1970, first Efimov state was observed in 2006 in ultracold cesium atoms near a Feshbach resonance. Since then, dozens of Efimov states have been identified in cold alkali and helium atoms.
In this talk, I will describe the intriguing history of the observation of the first Efimov state, unexpected Efimov universality, confirmation of Efimov geometric scaling, and various extensions of Efimov physics to complex systems.
