Following up with title and abstract! Ian ----------------- Title: Quantum vs. classical heat machines Speaker: David Gelbwaser-Klimovsky Abstract: Quantization of energy is a quintessential characteristic of quantum systems. In this talk, I will analyze its effects on the operation of Otto cycle heat machines and show that energy quantization alone may alter and increase machine performance in terms of output work, efficiency, and even operation mode. This difference in performance occurs in machines with inhomogeneous energy level scaling, while quantum machines with homogeneous level scaling behave like classical machines. These results demonstrate that quantum thermodynamics enable the realization of classically inconceivable Otto machines, such as those with an incompressible working substance. Finally, I will discuss the possibility to measure these effects experimentally using a laser-cooled trapped ion as a microscopic heat machine.
