Abstract
This paper extends the concept of shortcut-to-adiabaticity (STA) of the quantum Otto cycle to refrigerators. The authors find that the STA quantum refrigerator outperforms its conventional nonadiabatic counterpart, except for short cycle durations even when the energetic cost of the STA driving is included. In addition, the concept of quantum speed limits is employed to benchmark the upper bounds on the Otto refrigerator performance.
