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

Year: 2021

Type: article

Abstract: 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.
