AI 中文摘要
本研究探究了扩展非互易量子电池（QBs）的性能，以及其在储能和能量传输方面相较于互易充电与原始非互易电池的优势。在分析充电系统与外部泵浦的失谐后，我们发现共振是维持高能电池与高充电功率的关键因素；此外，充电器或电池的失谐决定了不同结构充电过程的稳定性。对电池稳态储能的研究表明，在弱局域环境中，单线或多线充电可实现近乎无限的储能，由此展现出扩展非互易量子电池显著的能量优势。最后，通过考量充电系统内的能量分布，我们观察到非互易充电具备互易充电无法企及的能量传输优势：前者在充电成本与储能容量间实现了后者无法匹配的综合平衡。作为一种新颖且更优的充电协议，本研究的发现有望为非互易充电的推广与实际应用提供有力参考。
英文摘要
This study investigates the performance of extended nonreciprocal quantum batteries (QBs), as well as its advantages in energy storage and energy transfer compared to reciprocal charging and the original nonreciprocal batteries. After analyzing the detuning between the charging system and the external pump, we discover that resonance is a key factor in maintaining high-energy batteries and high charging power; furthermore, the detuning of the charger or battery determines the stability of the charging process for different structures. Research on steady-state energy storage in batteries revealed that single-threaded or multi-threaded charging can achieve nearly infinite energy storage in weakly localized environments, thereby demonstrating the significant energy advantages of extended nonreciprocal quantum batteries. Finally, by considering the energy distribution within the charging system, we observe that nonreciprocal charging offers energy transfer advantages unmatched by reciprocal charging; the former achieves a comprehensive balance between charging cost and energy storage capacity that the latter cannot match. As a novel and superior charging protocol, our findings are expected to provide a potent reference for the promotion and practical implementation of nonreciprocal charging.
