AI 中文摘要

我们研究了嵌入驱动耗散光学微腔中的基于石墨烯的激子量子电池的充电和功提取特性。该系统由应变石墨烯中的一对能谷间激子组成,其中一个激子充当充电器,另一个充当量子电池,两者通过Tavis-Cummings相互作用耦合到共同的腔模。通过求解开放系统动力学,我们分析了作为可提取功度量的熵,并研究了相干和非相干泵浦、腔损耗以及微腔参数如何影响充电过程。我们的结果表明,电池呈现出一个瞬态熵峰值,随后弛豫到稳态,最大可提取功受到光与物质耦合强度的强烈控制。该研究揭示了高效充电的最佳状态,并证明了腔工程在增强激子量子电池中功存储方面的作用。

英文摘要

We study the charging and work-extraction properties of a graphene-based excitonic quantum battery embedded in a driven-dissipative optical microcavity. The system consists of a pair of intervalley excitons in strained graphene, where one exciton acts as the charger and the other as the quantum battery, both coupled to a common cavity mode through a Tavis-Cummings interaction. By solving the open-system dynamics, we analyze the ergotropy as a measure of extractable work and investigate how coherent and incoherent pumping, cavity loss, and the microcavity parameter influence the charging process. Our results show that the battery exhibits a transient ergotropy peak followed by relaxation to a steady state, with the maximum extractable work strongly controlled by the light-matter coupling strength. The study reveals an optimal regime for efficient charging and demonstrates the role of cavity engineering in enhancing work storage in excitonic quantum batteries.
