Multi-mode cooling of a Bose-Einstein condensate with linear quantum feedback
Zain Mehdi, Matthew L. Goh, Matthew J. Blacker +2
We theoretically investigate measurement-based feedback control over the motional degrees of freedom of an oblate quasi-2D atomic Bose-Einstein condensate (BEC) subject to continuo…
Fundamental Limits of Feedback Cooling Ultracold Atomic Gases
Zain Mehdi, Simon A. Haine, Joseph J. Hope +1
We investigate the fundamental viability of cooling ultracold atomic gases with quantum feedback control. Our study shows that the trade-off between the resolution and destructiven…
Feedback cooling Bose gases to quantum degeneracy
Matthew L. Goh, Zain Mehdi, Richard L. Taylor +5
Degenerate quantum gases are instrumental in advancing many-body quantum physics and underpin emerging precision sensing technologies. All state-of-the-art experiments use evaporat…
Mutual friction and diffusion of two-dimensional quantum vortices
Zain Mehdi, Joseph J. Hope, Stuart S. Szigeti +1
We present a microscopic open quantum systems theory of thermally-damped vortex motion in oblate atomic superfluids that includes previously neglected energy-damping interactions b…
Trap Frequency Measurement with a Pulsed Atom Laser
B. M. Henson, K. F. Thomas, Z. Mehdi +4
We describe a novel method of single-shot trap frequency measurement for a confined Bose-Einstein Condensate, which uses an atom laser to repeatedly sample the mean velocity of tra…
Superflow decay in a toroidal Bose gas: The effect of quantum and thermal fluctuations
Zain Mehdi, Ashton S. Bradley, Joseph J. Hope +1
We theoretically investigate the stochastic decay of persistent currents in a toroidal ultracold atomic superfluid caused by a perturbing barrier. Specifically, we perform detailed…
