Abstract

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.
