Performance Comparison of Quantum Otto and Stirling Engines Using Atom-Photon Interactions
Abstract
This article presents a comparative analysis of quantum Otto and Stirling engines using atom-photon interactions as the working substance. Two models are considered: a two-level Jaynes-Cummings system and a four-level atomic system confined in an optical cavity. The thermodynamic cycles are analyzed, highlighting the role of critical points, quantum correlations, and atom-field interactions in determining efficiency and work output. Our findings provide insights into the advantages and limitations of QHEs, offering a deeper understanding of energy conversion in quantum systems.
