Three-body physics in strongly correlated spinor condensates

POSTER

Abstract

We investigate bosonic spinor condensates in the largely unexplored strongly correlated regime where few-body aspects can play a central role in the properties and dynamics of the system through manifestations of Efimov physics. We have solved the three-body problem using the hyperspherical adiabatic representation, uncovering the multiple, co-existing families of Efimov states and the three-body scattering observables. The presence of these states can lead to non-trivial spin dynamics dominated by three-body correlations as well as the possibility of ultralong lived three-body bound states. The three-body contribution to the mean-field theory is constructed from the scattering observables, and its influence on the various phases of the spinor condensate is considered.
