Harnessing energy extracted from heat engines to charge quantum batteries [PDF]
arXiv, 2023 We explore the performance of three- and two-stroke heat engines with a qutrit working substance in charging two-level quantum batteries. We first classify the heat engines into two groups depending on their working methods. The first type of heat engine, the sequential engine, evolves through three distinct strokes, viz., heat, work, and cold strokes.

The asymmetric Otto engine: frictional effects on performance bounds and operational modes [PDF]
arXiv, 2023 We present a detailed study of an asymmetrically driven quantum Otto engine with a time-dependent harmonic oscillator as its working medium. We obtain analytic expressions for the upper bounds on the efficiency of the engine for two different driving schemes having asymmetry in the expansion and compression work strokes.
