论文摘要
Usha devi等人早些时候已经对旋转挤压的性质进行了两个旋转的耦合状态。 al。 (J.Phys。A:Math。Gen。365333(2003))。在本文中,我们将这项研究扩展到了两个Spin-1系统的耦合状态。在这里,我们表明,两个Spin-1状态的直接产物表现出挤压,与两个旋转器的直接产物不同。我们研究了两个Spin-1系统的不可分割的耦合状态的挤压性质,并确定了负责挤压存在的参数。我们还提供了通过外部互动来生成它们的方法。
The nature of spin squeezing has been studied earlier for a coupled state of two spinors by Usha Devi et. al. (J. Phys. A: Math. Gen. 36 5333 (2003)). In this paper, we extend this study to a coupled state of two spin-1 systems. Here, we show that the direct product of two spin-1 states exhibits squeezing unlike the direct product of two spinors. We investigate the nature of squeezing for non-separable coupled state of two spin-1 systems and identify the parameters which are responsible for the existence of squeezing. We also provide ways to generate them by external interactions.
