Enhanced squeezing for quantum gravimetry in a Bose-Einstein condensate with focussing
Lewis A. Williamson, Karandeep Gill, Andrew J. Groszek +2
Free-fall atom interferometers offer a powerful platform for accurate, absolute gravitational sensing. Szigeti et al. [Phys. Rev. Lett. 125, 100402 (2020)] recently proposed a quan…

Polar core vortex dynamics in disc-trapped homogeneous spin-1 Bose-Einstein condensates
Matthew Edmonds, Lewis A. Williamson, Matthew J. Davis
We study the dynamics of polar core vortices in the easy plane phase of an atomic spin-1 Bose-Einstein condensate confined in a two-dimensional disc potential. A single vortex move…
