We propose a stable charging scheme for a quantum battery in which the stable energy transfer of a noninteracting quantum charger-battery is induced by a common photonic band gap (PBG). By manipulating the transition frequency of the quantum battery to form multiple bound states, it is found that the capability of stable charging can be obtained without direct interaction between the quantum battery and the quantum charger. Among them, the formation of two bound states results in a lossless Rabi-like oscillatory behavior of the energy exchange. The formation of three bound states leads to a continuous collapse-revival process based on the oscillation of the stored energy. Particularly, the formation of three bound states also significantly enhances the energy extraction capability of the quantum battery. In addition, the stable charging scheme proposed in this paper can be further optimized from the perspective of environmental engineering. The expansion of the forbidden band gap width of the PBG environment not only enlarges the regulatory region for the formation of multiple bound states but also improves energy storage and extraction work.
我们提出了一种用于量子电池的稳定充电方案，其中非相互作用量子充电器 - 电池的稳定能量转移由共同的光子带隙（PBG）诱导。通过操纵量子电池的跃迁频率以形成多个束缚态，发现无需量子电池与量子充电器之间的直接相互作用即可获得稳定充电能力。其中，两个束缚态的形成导致能量交换呈现无损拉比型振荡行为。三个束缚态的形成导致基于存储能量振荡的连续坍缩 - 复苏过程。特别地，三个束缚态的形成还显著增强了量子电池的能量提取能力。此外，本文提出的稳定充电方案可从环境工程角度进一步优化。PBG环境禁带宽度的扩大不仅扩大了形成多个束缚态的调控区域，还提高了能量存储和提取效率。
