Correlated quantum engines defy Carnot limits at the atomic scale

University of Stuttgart researchers demonstrate that at atomic scales, quantum correlations between particles allow correlated quantum engines to exceed the traditional Carnot efficiency limit, by harvesting work from correlations in addition to heat; this generalizes thermodynamics for tiny, strongly correlated systems and could enable ultra-efficient nanoscale motors and quantum devices.

"Revolutionary Micro Heat Engine Shatters Thermodynamic Boundaries"

Scientists have developed a micro heat engine that challenges the Carnot limit by achieving high efficiency and power at the microscopic level. This engine operates on a single colloidal particle directed by a laser beam and manipulated by an electric field, achieving efficiency near 95% of the Carnot limit. This breakthrough overturns the belief that high power and high efficiency are mutually exclusive, potentially leading to the development of more energy-efficient devices in the future.
