Dynamics of Heisenberg XYZ two-spin quantum battery

Abstract

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.
