具有边界的简单自旋网络中的纠缠

Entanglement in simple spin networks with a boundary

Yi Ling, Meng-He Wu, Yikang Xiao

摘要:

本文研究了一类简单的具有悬挂边的自旋网络中边界态的二体纠缠,其中两个互补部分由两个或多个悬挂边连接。首先,在不考虑缠绕纠缠的情况下,考虑了自旋纠缠。通过数值模拟,我们发现纠缠熵通常依赖于群元。更重要的是,当考虑到缠绕纠缠时,我们发现一般不可能将总的纠缠熵分解为边自旋的贡献和顶点缠绕的贡献.这些情况与两个顶点由一条边连接的情况相反。

英文摘要:

We investigate the bipartite entanglement for the boundary states in a simple type of spin networks with dangling edges, in which the two complementary parts are linked by two or more edges. Firstly, the spin entanglement is considered in the absence of the intertwiner entanglement. By virtue of numerical simulations, we find that the entanglement entropy usually depends on the group elements. More importantly, when the intertwiner entanglement is taken into account, we find that it is in general impossible to separate the total entanglement entropy into the contribution from spins on edges and the contribution from intertwiners at vertices. These situations are in contrast to the case when the two vertices are linked by a single edge.
