vortex fluid

New publication on vortex fluids in Physical Review Research!

We have a new publication on vortex fluids in the open access Physical Review Research! Oliver Stockdale and the theory team have shown that an expanding vortex cluster in a 2D superfluid forms a Rankine vortex, suported by experimental measurements. This process is forbidden in classical fluids due to viscosity.

Giant vortex clusters in a two-dimensional quantum fluid

Our research on Onsager vortex clusters has just been published in Science​. Using our optical control of the BEC, we have injected high energy vortex clusters and have shown they are stable against decay.

Phase Imprinting in a Scanning Ring Trap

Our results on phase imprinting in a scanning ring trap have been published in Physical Review A. We find that unidirectional scanning leads to a non-trivial phase profile of the condensate that can be approximated analytically using the concept of phase imprinting. This could be used to imprint persistent currents into a ring, or for schemes to provide synthetic rotation for interferometer characterisation. By adapting a bidirectional scan, the phase imprint can be periodically cancelled.
