摘要：
Multipartite nonlocality is a measure of multipartite quantum correlations. In this paper, we investigate multipartite nonlocality in a spin-
$$\frac{1}{2}$$
XXZ model on a one-dimensional (1D) infinite-size zigzag lattice. In the ground states, the model can undergo topological-type quantum phase transitions (QPTs) between a singlet dimer (SD) phase and an even-parity dimer (ED) phase. Two nonlocality measures
$${\mathcal {S}}_o$$
(defined on the odd-bond subchains) and
$${\mathcal {S}}_e$$
(defined on the even-bond subchains) are used to characterize these top...
