摘要

人们对自旋系统进行了广泛的研究，以了解量子电池的机制，即使在封闭系统中，量子电池也显示出比经典电池充电更快的能力。然而，量子电池的内部动力学会显著影响其性能，因此了解各种参数的影响至关重要。在本研究中，我们以双自旋Heisenberg XYZ系统为研究对象，考察了自旋相互作用的各向异性和外部磁场等关键因素，以优化功输出以确保有效充电。

Dynamics of Heisenberg XYZ two-spin quantum battery

Spin systems have been extensively studied to understand the mechanisms of quantum batteries, which have shown the ability to charge faster than classical counterparts, even in closed systems. However, the internal dynamics of quantum batteries can significantly affect their performance, making it crucial to understand the influence of various parameters. In this study, we focus on a two-spin Heisenberg XYZ system, examining key factors such as anisotropy in spin interactions and external magnetic field to optimize work output to ensure effective charging.

期刊介绍： Physica A: Statistical Mechanics and its Applications Recognized by the European Physical Society Physica A publishes research in the field of statistical mechanics and its applications. Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents. Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
