Equilibrium and Non-Equilibrium Condensation Phenomena in Tuneable 3D and 2D Bose Gases

Abstract

We have investigated a range of equilibrium and non-equilibrium many-body phenomena, trapping ultracold atomic gases indifferent geometries including both 3 and 2 spatial dimensions, and with both the conventional harmonic trap and a newly developed "box trap". With the 3d harmonic trap, we observed a new "superheated Bose-condensed gas" which remains condensed above the expected critical temperature, and performed one of the first studies of the strongly-interacting "unitary" Bose gas. With the 2d harmonic trap we showed how the interaction-driven BKT phase is connected with purely statistical theory, and with the 3d box trap we created the world's first atomic BEC in a quasi-uniform potential.
