Dynamical interplay of few-body correlations in a thermal unitary Bose gas

Abstract

We study the growth of few-body correlations in an ultracold Bose gas quenched to unitarity. This is encoded in the dynamics of the two- and three-body contacts. By connecting many-body correlations dynamics with few-body models, we map out signatures of the Efimov effect. For the thermal resonantly interacting Bose gas where the contact dynamics have been measured experimentally, we find that atom-bunching leads to an enhanced growth of few-body correlations. These atom-bunching effects also highlight the interplay between few-body correlations that occurs before genuine many-body effects enter on Fermi timescales.
