单轴扭曲哈密顿量系统中的量子纠缠

摘要

We investigate quantum entanglement in one -axis twisting Hamiltonian system with two squeezing parameters .By analytical and numerical calculation , we see that one may enhance the entangled degree of the system by adding the total number of particles and appropriately decreasing the strength of the nonlinear interaction .%利用两种压缩参数研究单轴扭曲哈密顿量系统中的量子纠缠。通过解析求解和数字计算，发现可以通过增加系统的粒子数和适当减弱线性相互作用强度提高系统的纠缠程度。
