摘要

在本文中，我们提出了一个模型来研究开放量子电池的充电过程，而不使用外部源，在热环境诱导的退相干框架内。它包括考虑一个开放的量子电池，通过一个辅助的两级量子充电器与环境相互作用。本研究的重点是一种可行的充电装置，我们研究了量子电池与周围环境之间的信息交换、功提取及其最大量，即自恋性。我们的研究结果表明，在非马尔可夫状态下，自恋性和内能基本上比马尔可夫状态下增强，包括相干性及其对电池动力学的时间导数。

Enhancing ergotropy of quantum batteries through coherence and non-Markovianity

In this paper, we propose a model to examine the charging process of an open quantum battery, without using an external source, within the framework of the decoherence induced by the thermal environment. It consists of considering an open quantum battery that interacts with its environment through an auxiliary two-level quantum charger. This study focuses on a feasible charging device, where we investigate the exchange of information, work extraction and its maximum quantity, namely ergotropy from the quantum battery to its surroundings. Our results demonstrate that the ergotropy and internal energy are basically enhanced in the non-Markovian regime more than the Markovian one, including coherence and its time-derivative on the battery’s dynamics.

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.
