Order from chaos: Observation of large-scale flow from turbulence in a two-dimensional superfluid
Shaun P. Johnstone, Andrew J. Groszek, Philip T. Starkey +3
Interacting systems driven far from equilibrium tend to evolve to steady states exhibiting large-scale structure and order. In two-dimensional turbulent flow the seemingly random s…
Motion of vortices in inhomogeneous Bose-Einstein condensates
Andrew J. Groszek, David M. Paganin, Kristian Helmerson +1
We derive a general and exact equation of motion for a quantised vortex in an inhomogeneous two-dimensional Bose-Einstein condensate. This equation expresses the velocity of a vort…
Vortex Thermometry for Turbulent Two-Dimensional Fluids
Andrew J. Groszek, Matthew J. Davis, David M. Paganin +2
We introduce a new method of statistical analysis to characterise the dynamics of turbulent fluids in two dimensions. We establish that, in equilibrium, the vortex distributions ca…
Onsager vortex formation in Bose-Einstein condensates in two-dimensional power-law traps
Andrew J. Groszek, Tapio P. Simula, David M. Paganin +1
We study computationally dynamics of quantised vortices in two-dimensional superfluid Bose-Einstein condensates confined in highly oblate power-law traps. We have found that the fo…
Emergence of order from turbulence in an isolated planar superfluid
Tapio Simula, Matthew J. Davis, Kristian Helmerson
We study the relaxation dynamics of an isolated zero temperature quasi-two-dimensional superfluid Bose-Einstein condensate (BEC) that is imprinted with a spatially random distribut…
A scripted control system for autonomous hardware timed experiments
P. T. Starkey, C. J. Billington, S. P. Johnstone +4
We present the labscript suite, an open-source experiment control system for automating shot-based experiments and their analysis. Experiments are composed as Python code, which is…
