We investigate the generation of nonclassical state via two-axis counter twisting interactions. By the bosonization method, we analytically and numerically calculate the spin squeezing parameter and the entanglement parameter. Its shows that the strength of the nonlinear interaction and the orientation of spin squeezing play important role in generating nonclassical states.

通过两轴反扭曲相互作用生成非经典状态

我们通过两轴反扭曲相互作用研究非经典状态的生成。通过玻色化方法，我们分析和数值计算了自旋挤压参数和纠缠参数。它表明非线性相互作用的强度和自旋挤压的方向在产生非经典态方面起着重要作用。
