量子电池可提取功的涨落和充电功率的界限

Fluctuations in Extractable Work and Bounds on the Charging Power of Quantum Batteries

Shang-Yung Wang

摘要:

由于最近关于自由能算子中的波动约束量子电池的充电功率的说法存在分歧,我们对原始推导进行了批判性分析。分析表明,上述主张并不适用于封闭和开放系统动力学。我们的研究结果表明,自由能算子是不是一个一致的量化运营商的工作内容的量子电池充电。

英文摘要:

Motivated by a recent disagreement about the claim that fluctuations in the free energy operator bound the charging power of a quantum battery, we present a critical analysis of the original derivation. The analysis shows that the above claim does not hold for both closed- and open-system dynamics. Our results indicate that the free energy operator is not a consistent quantifying operator for the work content of a charging quantum battery.
