Optimal energy storage and collective charging speedup in the central-spin quantum battery

Autor: Yang, Hui-Yu, Zhang, Kun, Wang, Xiao-Hui, Shi, Hai-Long

Quantum batteries (QBs) exploit principles of quantum mechanics to accelerate the charging process and aim to achieve optimal energy storage. However, analytical results for investigating these problems remain lacking due to the challenges associated

Autor: Yang, Hui-Yu, Shi, Hai-Long, Wan, Qing-Kun, Zhang, Kun, Wang, Xiao-Hui, Yang, Wen-Li

Publikováno v: Phys. Rev. A 109, 012204 (2024)

The Tavis-Cummings (TC) model, which serves as a natural physical realization of a quantum battery, comprises $N_b$ atoms as battery cells that collectively interact with a shared photon field, functioning as the charger, initially containing $n_0$ p

Entanglement, Coherence, and Extractable Work in Quantum Batteries

Autor: Shi, Hai-Long, Ding, Shu, Wan, Qing-Kun, Wang, Xiao-Hui, Yang, Wen-Li

Publikováno v: Phys. Rev. Lett. 129, 130602 (2022)

We investigate the connection between quantum resources and extractable work in quantum batteries. We demonstrate that quantum coherence in the battery or the battery-charger entanglement is a necessary resource for generating nonzero extractable wor

Entanglement and work extraction in the central-spin quantum battery

Autor: Liu, Jia-Xuan, Shi, Hai-Long, Shi, Yun-Hao, Wang, Xiao-Hui, Yang, Wen-Li

Publikováno v: Phys. Rev. B 104, 245418 (2021)

We consider a central-spin battery where $N_b$ central spins serve as battery cells and $N_c$ bath spins serve as charging units. It is shown that the energy stored in the battery that can be extractable is quantified by the ergotropy, and that batte
