针对量子电池中阻塞效应阻碍能量积累的问题，提出基于亮-暗相互作用和等间距缀饰暗态的反阻塞充电协议，实现至少20倍能量存储增强，并可在坏腔极限下实现超扩展充电特性。
AI 中文摘要
阻塞是一种一个粒子阻碍另一个粒子输运的现象，构成了介观和微观物理中的核心研究课题。得益于其独特的单粒子特性，它支撑了从量子计算到量子计量学的多种应用。然而，在量子能量存储设备（即量子电池）的背景下，由固有能级分裂触发的阻塞反而对能量积累不利。在此，我们提出了一种通过精心设计亮-暗相互作用实现的反阻塞充电协议。该精细结构基于一组等间距的缀饰暗态，开辟了新的充电通道，促进了反阻塞能量流，并且相较于拉比劈裂阻塞设计，在能量存储方面至少实现了20倍的增强。此外，我们进一步展示了通过在坏腔极限下操作系统，可实现超扩展（二次）充电特性。鉴于其固有的普适性，我们的方案为高性能量子能量架构提供了一条通用且可行的途径。
英文摘要
Blockade, a phenomenon in which one particle hinders the transport of another, constitutes a core research topic in mesoscopic and microscopic physics. Benefiting from the unique single-particle characteristics, it underpins versatile applications spanning from quantum computation to quantum metrology. Nevertheless, in the context of quantum energy?storage devices, i.e., quantum batteries (QBs), blockade triggered by the intrinsic level splitting is in turn detrimental to energy accumulation. Here we propose an antiblockade charging protocol enabled by deliberately engineering a bright-dark interaction. Rooted in a manifold of equally-spaced dressed-dark states, this elaborate configuration opens up a new charging channel facilitating an antiblockade energy flow and outperforms the Rabi-split blockade design with at least a 20-fold enhancement in energy storage. Additionally, we further illustrate the achievement of superextensive (quadratic) charging characteristic by operating the system in the bad-cavity limit. In view of its inherent generality, our scheme offers a universal and feasible pathway toward high-performance quantum energy architectures.
