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…

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…
