We propose a method for engineering spin dynamics in ensembles of integer-spin atoms confined within a high-finesse optical cavity. Our proposal uses cavity-assisted Raman transitions to engineer a Dicke model for integer-spin atoms, which, in a dispersive limit, reduces to effective atom-atom interactions within the ensemble. This scheme offers a promising and flexible new avenue for the exploration of a wide range of spinor many-body physics. As an example of this, we present results showing that this method can be used to generate spin-nematic squeezing in an ensemble of spin-1 atoms. With realistic parameters, the scheme should enable substantial squeezing on time scales much shorter than current experiments with spin-1 Bose-Einstein condensates.

旋转气体中自旋动力学和压缩的腔QED工程

我们提出了一种方法，用于工程化局限在高精细光学腔内的整数自旋原子的集合体中的自旋动力学。我们的建议使用腔辅助拉曼跃迁为整数自旋原子设计Dicke模型，该模型在色散极限内减少了集合体中有效的原子-原子相互作用。该方案为探索多种旋子多体物理学提供了一种有希望且灵活的新途径。例如，我们提供的结果表明，该方法可用于在spin-1原子的整体中生成自旋向列型压缩。有了现实的参数，该方案应该能够在时间尺度上进行实质性的压缩，而压缩的时间比目前使用spin-1 Bose-Einstein凝聚物进行的实验要短得多。
