Spin Squeezing in Two-Species Bose-Einstein Condensate

We investigate spin squeezing dynamics of a system of two-species Bose-Einstein condensate with weak nonlinear interatomic interactions and Josephson-like tunneling. Numerical analysis of spin squeezing is presented. It is shown that spin squeezing is independent of Josephson-like coupling and the i...

Description
Summary:We investigate spin squeezing dynamics of a system of two-species Bose-Einstein condensate with weak nonlinear interatomic interactions and Josephson-like tunneling. Numerical analysis of spin squeezing is presented. It is shown that spin squeezing is independent of Josephson-like coupling and the increasing total atomic number causes weaker spin squeezing and shorter squeezing time.
