Shortcut-to-adiabaticity Otto engine: A twist to finite-time thermodynamics
Shortcut-to-adiabaticity Otto engine: A twist to finite-time thermodynamics
We consider a finite-time Otto engine operating on a quantum harmonic oscillator and driven by shortcut-to-adiabaticity (STA) techniques to speed up its cycle. We study its efficiency and power when internal friction, time-averaged work, and work fluctuations are used as quantitative figures of merit, showing that time-averaged efficiency and power …
