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…

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…

Universal relations and bounds for fluctuations in quasistatic small heat engines
Kosuke Ito, Guo-Hua Xu, Chao Jiang +4
The efficiency of any heat engine, defined as the ratio of average work output to heat input, is bounded by Carnot's celebrated result. However, this measure is insufficient to cha…
