摘要

我们研究了海森堡 XYZ 系统中的热量子相干性和磁量子相干性。为此，我们采用了三种测量方法：L1 规范相干性、相对熵相干性和雷尼互信息（RMI）。通过这些测量方法，我们可以准确地描述海森堡 XYZ 系统的量子行为。在描述过程中，我们既发现了相似性，也发现了独特性。在非均匀磁场下，磁场可以增强不同系数 α 的 RMI。本文详细介绍了所有分析和数值结果。

Quantum coherence and Rényi mutual information in Heisenberg XYZ system under non-uniform field

We investigate the thermal and magnetic quantum coherence in the Heisenberg XYZ system. To accomplish this, we employ three measures: the L1 norm coherence, the relative entropy coherence, and the Rényi mutual information (RMI). By performing these measures, we can accurately describe the quantum behaviors of the Heisenberg XYZ system. During the process of characterization, we have found both similarities and distinctive properties. Under a non-uniform field, the magnetic field can enhance the RMI for different coefficients α. All of the analytical and numerical results are described in details.
