Low-inelastic-rate Atom-Molecule Collisions in a Magnetic Trap

The study of low-temperature molecular collisions is a key step to understanding the fundamental processes in archetypal few-body systems, but also as a stepping stone to further cooling, whether sympathetic or evaporative. With the aim of building on our buffer-gas-loaded BEC work with metastable helium, we studied, both theoretically and experimentally, the collisional properties of...

Making Van Der Waals Molecules

Van der waals molecules involving helium as a partner are typically very weakly bound and exist only in non-equilibrium situations. Here, through re-analysis of Ag atom magnetic trap loss, a general method for creating, in equilibrium, a host of vdW molecules in the very low temperature (and high cooling capacity) conditions of dilution refrigerator cooled...
