Abstract

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.

非均匀场下海森堡 XYZ 系统的量子相干性和雷尼互信息

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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
