The Bose–Einstein Condensate Laboratory explores the fundamental physics and applications of ultracold degenerate atomic systems based at the University of Queensland, Brisbane.
Representing nearly the coldest physical systems ever observed, atomic Bose-Einstein condensates (BECs) are among the cleanest, most flexible, precisely controllable, and isolated quantum many-body systems available. The Atom Optics Lab utilises optical trapping techniques to precisely configure the trapping potential (container) in which the condensate is held. This facilitates precise and dynamic control of these quantum many-body systems. We have two BEC machines in our lab:
Our research focuses on studies of superfluid properties of BEC in ring traps and their applications for interferometry. We are also exploring two-dimensional quantum turbulence and superfluid transport for future atomtronic devices. In collaboration with theorists within EQUS and UQ, we are investigating the dynamics of non-equilibrium BECs in configured and time varying optical traps.
Our project is also part of the EQuS flagship research program in quantum thermodynamics. Utilising our developing model system of a two-component ultracold quantum gas, we aim for clear and convincing demonstrations and validation of the laws of quantum thermodynamics, and providing guiding principles for the continuing future miniaturisation of semiconductor electronics.
