摘要：

旋量玻色-爱因斯坦凝聚是量子光学领域的热点研究对象,同时在精密测量领域也被广泛应用.基于半经典的截断维格纳近似方法研究了F=1旋量玻色-爱因斯坦凝聚中的自旋向列压缩.通过数值模拟得到自旋向列压缩的动力学行为,并在自旋向列球上展示了自旋向列压缩的物理特性.最后研究了系统在任意初始态下的自旋向列压缩行为.研究展现了旋量玻色-爱因斯坦凝聚在精密测量领域的潜在应用.

Spinor Bose-Einstein condensate has become a hot research topic in quantum optics,widely used in precision measurement.In this paper,based on the semiclassical truncated Wigner approximation,the spin-nematic squeezing in the F=1 spinor Bose-Einstein condensate is studied.The dynamic behaviors of the spin-nematic squeezing are obtained by numerical simulation,and the physical properties of the spin-nematic squeezing are demonstrated on the spin-nematic sphere.Finally,we also study the behaviors of the spin-nematic squeezing of the system under arbitrary initial states.Our research demonstrates the potential applications of spinor Bose-Einstein condensate in precision measurement.
