AMO Seminar: Victor Colussi, Infleqtion/ColdQuanta, “Few-Body Correlations in Strongly Interacting Quantum Gases”

What happens when particles cease to become separate objects and begin to feel their surrounding neighbors? Understanding this transformation in the presence of strong correlations has remained a difficult question across many branches of physics. I will describe how this few-to-many body question arises in context of strongly interacting atomic Bose gases. Here the occurrence of the Efimov effect introduces an infinity of Borromean few-body bound states destabilizing the system while opening up the possibility of unusual quantum fluids with few-body origins.
