Event Details & Abstract: 

Recent theoretical advances have greatly broadened our ability to understand and control atomic behavior in the context of ultracold gases. Increasingly, these gains are being translated into prospects for developing the next generation of atomic clocks, for creating novel phases of atomic gases, and for manipulating chemical reaction dynamics. In this talk, I will present a few-body physics perspective of ultracold quantum gases, at the heart of which lies physics surrounding the mysterious "Efimov" effect. Predicted about 40 years ago, the Efimov effect is one of the most counterintuitive quantum phenomena that manifests itself in a "simple" few-particle system. I will explain the physics of this effect, how to treat it numerically, and some of our preliminary results towards the development of coherent control of few-body Efimov physics and its collisional properties. Such control can be instrumental for various experiments in ultracold quantum gases and open up ways to produce exotic quantum phases of matter.
