We derive the general probability distribution function of stochastic work for quantum Otto engines in which both isochoric and driving processes are irreversible due to finite time duration. The time-dependent fluctuations, average work, thermodynamic efficiency explicitly obtained a complete cycle operating with an analytically solvable two-level system. effects irreversibility originating fr...

The optimal control of open quantum systems is a challenging task but has key role in improving existing information processing technologies. We introduce general framework based on Reinforcement Learning to discover thermodynamic cycles that maximize the power out-of-equilibrium heat engines and refrigerators. apply our method, soft actor-critic algorithm, three systems: benchmark two-level sy...

We investigate the quantum thermodynamic cycle of a heat engine carrying out an Otto cycle. use thermal properties moving bath with relativistic velocity respect to cold bath. As working medium, we two-level system and harmonic oscillator that interact hot respectively. In current work, is studied in high low temperatures regime. Using thermodynamics theory open systems obtain total produced ef...

Abstract Long-range interacting quantum devices provides a promising route for technology applications. Here, the presence of long-range interactions is shown to enhance performances heat engine featuring many-body working substance. We focus on paradigmatic example Kitaev chain undergoing Otto cycle and show that substantial thermodynamic advantage may be achieved as range among its constituen...
