文摘

We propose an experimentally feasible setup for producing dynamically spin squeezed state of two Bose-Einstein Condensates (BECs) with Josephson-like coupling. The spin squeezing parameter is independent of Josephson-like coupling and the stronger squeezing can be achieved by increasing the number of the atoms.
