Turbulence in Quantum Gases: Vortices, Waves, and Cascades
Ashton S. Bradley, Tyler W. Neely, Xiaoquan Yu +1
We review turbulence in ultracold quantum gases, using the scalar contact-interaction Bose-Einstein condensate as the reference system for quantized circulation, compressibility, v…
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…
Vortex generation in stirred binary Bose-Einstein condensates
Anacé N. da Silva, R. Kishor Kumar, Ashton S. Bradley +1
The dynamical vortex production, with a trap-confining time-dependent stirred potential, is studied by using mass-imbalanced cold-atom coupled Bose-Einstein condensates (BEC). The…
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…
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…
Turbulent relaxation to equilibrium in a two-dimensional quantum vortex gas
Matthew T. Reeves, Kwan Goddard-Lee, Guillaume Gauthier +9
We experimentally study emergence of microcanonical equilibrium states in the turbulent relaxation dynamics of a two-dimensional chiral vortex gas. Same-sign vortices are injected…
