In quantum mechanics, quantum batteries are devices that can store energy by utilizing the principles of quantum mechanics. While quantum batteries has been investigated largely theoretical, recent research indicates that it may be possible to implement such a device using existing technologies. The environment plays an important role in the charging of quantum batteries. If a strong coupling exists between the environment and the battery, then battery can be charged properly. It has also been demonstrated that quantum battery can be charged even in weak coupling regime just by choosing a suitable initial state for battery and charger. In this study, we investigate the charging process of open quantum batteries mediated by a common dissipative environment. We will consider a wireless-like charging scenario, where there is no external power and direct interaction between charger and battery. Moreover, we consider the case in which the battery and charger move inside the environment with a particular speed. Our results demonstrate that the movement of the quantum battery inside the environment has a negative effect on the performance of the quantum batteries during the charging process. It is also shown that the non-Markovian environment has a positive effect on improving battery performance.
在量子力学中,量子电池是利用量子力学原理来存储能量的设备。虽然量子电池在很大程度上是理论上的研究,但最近的研究表明,使用现有技术实现这样的设备是可能的。环境在量子电池的充电过程中起着重要的作用。如果环境和电池之间存在强耦合,那么电池就可以被正确地充电。此外,还已经证明,通过为电池和充电器选择合适的初始状态,即使在弱耦合情况下,量子电池也可以被充电。在这项研究中,我们研究了由常见耗散环境介导的开放式量子电池的充电过程。我们将考虑一种类似于无线充电的场景,其中充电器和电池之间没有外部电源和直接相互作用。此外,我们还考虑了电池和充电器在环境中以特定速度移动的情况。我们的结果表明,在充电过程中,量子电池在环境中的运动对量子电池的性能有负面影响。此外,非马尔可夫环境对提高电池性能有积极影响。
