Optimal energy storage in the Tavis-Cummings quantum battery

Hui-Yu Yang, Hai-Long Shi, Qing-Kun Wan +3

The Tavis-Cummings (TC) model, which serves as a natural physical realization of a quantum battery, comprises atoms as battery cells that collectively interact with a shared…

Entanglement and work extraction in the central-spin quantum battery

Jia-Xuan Liu, Hai-Long Shi, Yun-Hao Shi +2

We consider a central-spin battery where central spins serve as battery cells and bath spins serve as charging units. It is shown that the energy stored in the battery…

Entanglement, Coherence, and Extractable Work in Quantum Batteries

Hai-Long Shi, Shu Ding, Qing-Kun Wan +2

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 entan…

Coherence of an extended central spin model with a coupled spin bath

Pengcheng Lu, Hai-Long Shi, Like Cao +4

We study an extended central spin model with an isotropic nearest-neighbour spin-exchange interaction among the bath spins. The system is controllable by external magnetic fields a…

Decoherence dynamics of entangled quantum states in the central spin model

Qing-Kun Wan, Hai-Long Shi, Xu Zhou +2

Maintaining coherence of a qubit is of vital importance for realizing a large-scale quantum computer in practice. In this work, we study the central spin decoherence problem in the…

Quantum Coherence in a Quantum Heat Engine

Yun-Hao Shi, Hai-Long Shi, Xiao-Hui Wang +4

We identify that quantum coherence is a valuable resource in the quantum heat engine, which is designed in a quantum thermodynamic cycle assisted by a quantum Maxwell's demon. This…
