Everything radiates heat, and when quantum objects radiate heat, they can reveal properties that are hard to detect without being destroyed in the process: observing how an object heats up and cools down can diagnose its quantum nature.
Thermodynamics, the study of the flow of heat between objects, was developed to better understand engines, but Patrick Lipka-Bartsik and his colleagues at the University of Geneva in Switzerland wanted to apply it…
