Heat is energy, called thermal energy, and is just one type of energy. Other types of energy include electromagnetic, nuclear, sonic, gravitational, mechanical, chemical, potential and kinetic energy.
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, ...
