Dynamical Generation of Spin Squeezing in Ultracold Dipolar Molecules

We study a bulk fermionic dipolar molecular gas in the quantum degenerate regime confined in a two-dimensional geometry. Using two rotational states of the molecules, we encode a spin 1/2degree of freedom. To describe the many-body spin dynamics of the molecules, we derive a long-range interacting XXZmodel valid in the regime where motional degrees of freedom are frozen. Because of the spatially extended nature of the harmonic oscillator...
