Scaling law of asymptotic freedom in collective charging of quantum batteries
Gentaro Watanabe, Chunlin Chen, B. Prasanna Venkatesh
We establish a universal scaling law for collective charging of quantum batteries, independent of microscopic details. We prove that the ergotropy-to-energy ratio approaches unity…
Unified geometric formalism for dissipation and its fluctuations in finite-time microscopic heat engines
Gentaro Watanabe, Guo-Hua Xu, Yuki Minami
Microscopic heat engines operate in regimes where thermodynamic quantities fluctuate strongly, making stochastic effects an essential aspect of their performance. However, existing…
Asymptotic freedom in the dephased charging of quantum batteries
Chayan Purkait, B. Prasanna Venkatesh, Gentaro Watanabe
Quantum batteries, small-scale energy storage devices based on quantum systems, offer the potential for enhanced charging performance through quantum effects such as coherence and…
Dephasing Enabled Fast Charging of Quantum Batteries
Rahul Shastri, Chao Jiang, Guo-Hua Xu +2
We propose and analyze a universal method to obtain fast charging of a quantum battery by a driven charger system using controlled, pure dephasing of the charger. While the battery…
Quantum fluctuation theorems and power measurements
B. Prasanna Venkatesh, Gentaro Watanabe, Peter Talkner
Work in the paradigm of the quantum fluctuation theorems of Crooks and Jarzynski is determined by projective measurements of energy at the beginning and end of the force protocol.…
Transient quantum fluctuation theorems and generalized measurements
B. Prasanna Venkatesh, Gentaro Watanabe, Peter Talkner
The transient quantum fluctuation theorems of Crooks and Jarzynski restrict and relate the statistics of work performed in forward and backward forcing protocols. So far these theo…
