Abstract
We investigate many-body spin squeezing dynamics in an model with interactions that fall off with distance as in and 3 spatial dimensions. In stark contrast to the Ising model, we find a broad parameter regime where spin squeezing comparable to the infinite-range limit is achievable even when interactions are short ranged, . A region of “collective” behavior in which optimal squeezing grows with system size extends all the way to the limit of nearest-neighbor interactions. Our predictions, made using the discrete truncated Wigner approximation, are testable in a variety of experimental cold atomic, molecular, and optical platforms.
