二体纠缠与单粒子态的局域化

Bipartite entanglement and localization of one-particle states

Haibin Li, Xiaoguang Wang, Bambi Hu

摘要:

研究了一般单粒子态中的两体纠缠,发现描述两体纠缠的线性熵与表征态局域化的粒子数比直接相关。态的扩展程度越大,态的纠缠度就越大。我们应用一般形式研究了一维Harper模型中纠缠的基态和动力学性质。

英文摘要:

We study bipartite entanglement in a general one-particle state, and find that the linear entropy, quantifying the bipartite entanglement, is directly connected to the paricitpation ratio, charaterizing the state localization. The more extended the state is, the more entangled the state. We apply the general formalism to investigate ground-state and dynamical properties of entanglement in the one-dimensional Harper model.
