Self-induced spatial dynamics to enhance spin-squeezing via one-axis twisting in a two-component Bose-Einstein condensate

Haine, S. A.; Lau, J.; Anderson, R. P.; Johnsson, M. T.


We theoretically investigate a scheme to enhance spin squeezing in a two-component Bose-Einstein condensate (BEC) by utilizing the inherent mean-field dynamics of the condensate. Due to the asymmetry in the scattering lengths, the two components exhibit density oscillations where they spatially separate and recombine. The effective non-linearity responsible for spin squeezing is increased by up to three orders of magnitude when the two components spatially separate \cite{treutlein2010}....[Show more]
