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.

Onsager's negative temperature vortex clusters

Our recent work on the first observations of Onsager's negative temperature vortices has appeared on the arXiv. These high-energy states of vortex matter were first predicted by Lars Onsager some 70 years ago in 1949.

The ART of BEC

Though the DMD is a binary device, the techniques of error-diffusion (halftoning) can be used to produce trapping potentials with intermediate levels. With the help of Dr. Jinyang Liang at Caltech, we have recently refined our techniques for producing grayscale condensates.
