Enhancing the efficiency of open quantum batteries via adjusting the classical driving field

In the context of quantum information, a quantum battery refers to a system composed of quantum particles that can store and release energy in a way that is governed by the principles of quantum mechanics. The study of open quantum batteries is motivated by the fact that real-world quantum systems are almost never perfectly isolated from their environment. One important challenge in the study of open quantum batteries is to develop theoretical models that accurately capture the complex interactions between the battery and its environment. The goal of studying open quantum batteries is to develop practical methods for building and operating quantum devices that can store and release energy with high efficiency and reliability, even in the presence of environmental noise and other sources of decoherence. In this study, we will investigate the impact of the classical driving field on the charging and discharging processes of open quantum batteries. The application of a classical driving field can effectively regulate the charging and discharging processes of a battery, resulting in enhanced performance and increased efficiency. It will also be demonstrated that the efficiency of open quantum batteries is influenced by the detuning between the qubit and the classical driving field, as well as by the detuning between the central frequency of the cavity and the classical driving field. • Enhancing charging and work extraction process of open quantum battery. • Classical deriving field and charging and discharging performance of quantum battery. • Detuning between the quantum battery and the classical driving field. • Detuning between the central frequency of the cavity and the classical driving field.
