论文摘要
我们研究了在通用耗散环境介导的开放量子电池（QB）期间，马尔可夫和非马克维亚系统中熵不确定性的动力学。在非马克维亚政权中，电池几乎有效地充满了充满电，强大的非马克维亚物业有益于提高充电能力。此外，结果表明，能源的存储与充电器 - 保存和电池库的耦合密切相关。也就是说，充电器库库的更强耦合可改善储能。特别是，需要纠缠才能获得最多的能量，并伴随着最小紧密的熵结合。有趣的是，发现熵结合的紧密度可以被认为是不同充电过程中能量转移的良好指标，并且完整的能量转移始终与最紧密的熵结合对应。我们的结果提供了对实用充电过程中QB的最佳充电效率的见解。
We studied the dynamics of entropic uncertainty in Markovian and non-Markovian systems during the charging of open quantum batteries (QBs) mediated by a common dissipation environment. In the non-Markovian regime, the battery is almost fully charged efficiently, and the strong non-Markovian property is beneficial for improving the charging power. In addition, the results show that the energy storage is closely related to the couplings of the charger-reservoir and battery-reservoir; that is, the stronger coupling of a charger-reservoir improves energy storage. In particular, entanglement is required to obtain the most stored energy and is accompanied by the least tight entropic bound. Interestingly, it was found that the tightness of the entropic bound can be considered a good indicator of the energy transfer in different charging processes, and the complete energy transfer always corresponds to the tightest entropic bound. Our results provide insight into the optimal charging efficiency of QBs during practical charging.
