Spin quantum heat engines with shortcuts to adiabaticity
Spin quantum heat engines with shortcuts to adiabaticity
We consider a finite-time quantum Otto cycle with single- and two spin-$1/2$ systems as its working medium. To mimic adiabatic dynamics at a finite time, we employ a shortcut-to-adiabaticity technique and evaluate the performance of the engine including the cost of the shortcut. We compare our results with the true …
