Understanding Multichannel nature of Efimov physics with ultracold 7Li atoms

POSTER

Abstract

We present our current understanding of various aspects of Efimov physics originating from the complex multichannel hyperfine structure which further help us to understand puzzling 7Li experimental observations. Our results indicates that spin-exchange for 7Li atoms play an important role in the determination of Efimov resonances along with the narrow character of its Feshbach resonances. We show that the structure of three-body potentials is strongly dependent on the resonance width giving further insights to other atomic species.
