As the quenched unitary Bose gas evolves, the buildup of correlations leads to the formation of extended pairs bound purely by many-body effects, analogous to the phenomenon of Cooper pairing in the BCS regime of the Fermi gas. We study how correlation growth, bound pairs, and three-body losses emerge in the fraction of unbound atoms remaining post sweep, finding quantitative agreement with experiment and speculate on discrepancies. We also highlight more recent efforts to study effects of higher-order correlations in the many-body dynamics, including the Efimov effect. NWO Grant 680-47-623.
