Physicists found a way to see heat in empty space
Heat is supposed to need something to cling to, whether vibrating atoms in a metal rod or infrared light streaming from a hot stove. Yet a series of recent experiments suggests that empty space is not ...
The researchers have made a major advance in controlling radiative heat flow at the nanoscale by combining topological physics with thermal metaphotonics. Their study, published in npj Metamaterials, ...
