Finite-size reliability of homothetic quantum Otto engines
Gabriella G. Damas, Clebson Cruz, Norton G. de Almeida +2
Homothetic quantum Otto engines---where all populated energy gaps are rescaled by a common factor---provide a reference model in which the quasistatic stochastic efficiency is traj…

Coherence-Preserving Fluctuation Diagnostics for an Engineered Population-Inverted Qubit Otto Engine
Gabriella G. Damas, Norton G. de Almeida, Gao Xianlong +1
Finite-time quantum thermal machines require diagnostics beyond average work and efficiency, because microscopic engines operate in regimes where fluctuations, incomplete thermaliz…
