Radiation :: Quantized heat conduction by photons observed – Finland
In a recent experiment, to be published in Nature on Nov. 9, Dr. Matthias Meschke and professor Jukka Pekola, together with Dr. Wiebke Guichard, a coworker from French CNRS, investigated heat exchange between two small pieces of normal metal, connected to each other only via superconducting leads. The results demonstrate that at very low temperatures heat is transferred by electromagnetic radiation.
