论文摘要
我们研究了在两种不同的情况下由常见耗散环境介导的开放量子电池的充电过程。在第一种情况下，我们考虑了在非马克维亚环境的存在下的量子充电器电池模型。如果可以在强大的耦合方面将电池充电，而没有任何外部功率，并且与充电器的任何直接互动，即发生无线式充电。环境在电池充电中起着重要作用，而在较弱的耦合方案中，这种环境并非发生。在第二种情况下，我们通过考虑在马尔可夫动力学的存在下考虑一个两分的系统，展示了个体和集体自发发射速率对量子电池充电过程的影响。我们的结果表明，通过采用阻尼不足的政权和/或强大的外部场，可以在马尔可夫动力学中令人满意地充电开放电池。我们还考虑了次级状态和一个中间政权，提出了强大的电池。此外，我们提出了一个实验设置，以在第一种情况下探索麦角镜。
We study the charging process of open quantum batteries mediated by a common dissipative environment in two different scenarios. In the first case, we consider a quantum charger-battery model in the presence of a non-Markovian environment. Where the battery can be properly charged in a strong coupling regime, without any external power and any direct interaction with the charger, i.e., a wireless-like charging happens. The environment plays a major role in the charging of the battery, while this does not happen in a weak coupling regime. In the second scenario, we show the effect of individual and collective spontaneous emission rates on the charging process of quantum batteries by considering a two-qubit system in the presence of Markovian dynamics. Our results demonstrate that open batteries can be satisfactorily charged in Markovian dynamics by employing an underdamped regime and/or strong external fields. We also present a robust battery by taking into account subradiant states and an intermediate regime. Moreover, we propose an experimental setup to explore the ergotropy in the first scenario.
