Quantum Heat Engines and the Generalized Uncertainty Principle

We study the effects of the generalized uncertainty principle (GUP) on the efficiency of quantum heat engines based on a particle in an infinite square well using the partition function approach. In particular, we study the Carnot and Otto heat engines. For the system we used, the GUP-corrected efficiencies turned out to be lower than efficiencies without the GUP effects. However, as expected, GUP effects increase as the temperature of the cold heat bath decreases and as the width of the potential well decreases.
