Event Details & Abstract: 

In this relatively informal (unpolished) talk I will present two recent experiments on strongly interacting Bose gases. In one experiment we use Ramsey interferometry to measure both two- and three-body contacts in a harmonically trapped thermal gas with resonantly enhanced interactions [1]. In the second experiment we use Bragg spectroscopy to study a homogeneous (box-trapped) strongly interacting BEC. From these measurements we extract complementary information about the two-body contact, structure factor and quantum depletion. Our measurements are generally in excellent agreement with theory, but some things we still do not understand.
