Enshrined by the laws of Austrian physicists Josef Stefan and Ludwig Boltzmann in the late 19th Century, scientists have long understood the general principles of heat-energy transfer between the sun and planet Earth.

But at much closer separations, where photons can effectively “tunnel” between two bodies, the maximum rate and size at which two objects – one hot, one cold – can transfer heat has remained unknown.

From their emerging field of near-field nanophotonics, a group of Yale scientists have taken a new step in advancing the ‘Stefan-Boltzmann law’ by creating a mathematical framework to identify the upper bounds of light interactions and radiative energy transfer. Read full article at YaleNews.

Hui Cao, newly named as the John C. Malone Professor of Applied Physics and of Physics, focuses her research on mesoscopic physics and nanophotonics. Read full article at Yale News.
