Ergotropy of nonequilibrium steady states beyond the full secular approximation
Xing-Xing Hu, Hui-Yu Yang, Kun Zhang +1
Understanding the generation and activation of ergotropy, the maximum work extractable by cyclic unitary operations, is central to quantum battery research. Positive-temperature th…
Emergent mirror symmetry in the optimization of the central-spin quantum battery
Hui-Yu Yang, Kun Zhang, Xiao-Hui Wang +1
Quantum batteries provide a useful setting for exploring nonequilibrium many-body effects in energy storage. Here we investigate the optimization of a quantum battery based on the…
Optimal energy storage and collective charging speedup in the central-spin quantum battery
Hui-Yu Yang, Kun Zhang, Xiao-Hui Wang +1
Quantum batteries (QBs) exploit principles of quantum mechanics to accelerate the charging process and aim to achieve optimal energy storage. However, analytical results for invest…
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…
