一维横场伊辛模型中的局域纠缠和量子相变

Local entanglement and quantum phase transition in 1D transverse field Ising model

Shi-Quan Su, Jun-Liang Song, Shi-Jian Gu

摘要:

本文研究了一维横场伊辛模型的简单量子相变中相邻两个量子点与系统其余部分之间的纠缠。我们发现纠缠在临界点附近表现出有趣的标度性和奇异性,可以作为跃迁点的一个方便的标记。

英文摘要:

In this paper, we study the entanglement between two-neighboring sites and the rest of the system in a simple quantum phase transition of 1D transverse field Ising model. We find that the entanglement shows interesting scaling and singular behavior around the critical point, and then can be use as a convenient marker for the transition point.
