entanglement entropy

we calculate the quantities, such as the ground state energy, entanglement entropy and so on, and confirm that it is a first-order quantum phase transition.

通过计算系统的基态能量、基态纠缠等量我们证实该量子相变是一级相变。

especially, the atomic information entropy squeezing, the reduced entropy entanglement and the relative entropy entanglement, which form the theoretical basic of the works in the following chapters, are discussed in detail.

然后阐述了原子压缩与量子纠缠的基本理论。特别详细介绍了原子信息熵压缩、量子部分熵纠缠度和量子相对熵纠缠度，为下面章节的研究工作做理论准备。
