摘要：

We squeeze unconditionally the collective spin of a dilute ensemble of laser-cooled Rb-87 atoms using their interaction with a driven optical resonator. The shape and size of the resulting spin uncertainty region are well described by a simple analytical model [M.H. Schleier-Smith, I. D. Leroux, and V. Vuletic, arXiv: 0911.3936 [Phys. Rev. A (to be published)]] through 2 orders of magnitude in the effective interaction strength, without free parameters. We deterministically generate states with up to 5.6(6) dB of metrologically relevant spin squeezing on the canonical Rb-87 hyperfine clock transition.
