Exploring Efimov physics in three spin fermionic atomic gases

POSTER

Abstract

We explore three-body universal properties of ultracold collisions involving 6Li atoms in three different internal spin states. Our model is adjusted to reproduce the proper magnetic field dependence of both two-body scattering length and binding energies. We then apply the model to determine the three-body scattering properties. More specifically, we calculate three-body recombination and atom-dimer relaxation in order to test our theoretical description against the currently available experimental data, which indicate the existence of several features related to Efimov physics.
