The results of their study were released yesterday in the journal Physical Review Letters, published by the American Physical Society. People have studied classical metasurfaces for a long time, says Diego Dalvit, who works in the Condensed Matter and Complex Systems group at the Laboratory s Theoretical Division. But we came up with this new idea, which was to modulate in time and space the optical properties of a quantum metasurface tha

New advancement in Nanophotonics explains how collections of hot nanoparticles cool down

Date Time New advancement in Nanophotonics explains how collections of hot nanoparticles cool down Everyone has sat outside on a sunny day and been warmed by the sun’s rays. This happens through a process known as radiative heat transfer: the sun emits light (electromagnetic radiation), which travels to the Earth and heats up the objects that absorb it. Radiative heat transfer is also the mechanism behind thermal cameras. Every hot object, including human beings, emits light, allowing it to release heat and thermalize to the environment. The wavelengths, or colors of light that are emitted, depend on the temperature of the object, with the sun being hot enough to produce visible light and human bodies emitting light that is not visible to the eye but can be picked up by infrared sensors.
