Criticality and Spin Squeezing in the Rotational Dynamics of a BEC on a Ring Lattice
Michal Kolář, Tomáš Opatrný, Kunal K. Das
We examine the dynamics of circulating modes of a Bose-Einstein condensate confined in toroidal lattice. Nonlinearity due to interactions leads to criticality that separates oscill…

Spin squeezing by tensor twisting and Lipkin-Meshkov-Glick dynamics in a toroidal Bose-Einstein condensate with spatially modulated nonlinearity
Tomáš Opatrný, Michal Kolář, Kunal K. Das
We propose a scheme for spin-squeezing in the orbital motion of a Bose-Einstein condensate (BEC) in a toroidal trap. A circular lattice couples two counter-rotating modes and squee…
