Abstract

The tripartite quantum coherence for spin- $\frac{1}{2}$ and bipartite quantum coherence for spin-1 many-body systems are studied with the quantum renormalization group method to investigate the quantum criticality behaviour of both systems. We find both spin- $\frac{1}{2}$ and spin-1 systems exhibit quantum criticality behaviour after different number of iterations. However, the bipartite quantum coherence for spin-1 system reaches the quantum criticality behaviour in lesser number of iterations than the tripartite quantum coherence for spin- $\frac{1}{2}$ system. The quantum criticality behaviour of both systems is also investigated through non-analytic and the scaling behaviour of quantum coherence. Additionally, quantum correlations and quantum phase transition are observed to be more vigorous with higher spin comparatively to the number of parties (i.e., bipartite, tripartite, multipartite) involved in a quantum correlations.

自旋1多体系统中量子相干性和量子临界性的鲁棒性

利用量子重整化群方法研究了自旋-12多体系统的三部量子相干性和自旋-1多体系统的二部量子相干性，探讨了这两个系统的量子临界行为。我们发现自旋-12和自旋-1系统在不同的迭代次数后都表现出量子临界行为。然而，自旋-1系统的二部量子相干性比自旋-12系统的三部量子相干性在更少的迭代次数下达到量子临界行为。通过量子相干的非解析行为和标度行为研究了这两个系统的量子临界行为。此外，量子相关和量子相变被观察到具有更高的自旋，相对于量子相关中涉及的各方(即二方，三方，多方)的数量更有活力。
