Latest Photon Stories
Although Dark Energy and Dark Matter appear to constitute over 95 percent of the universe, nobody knows of which particles they are made up. Astrophysicists now crossed one potential Dark Matter candidate – the Dark Photon or U boson – off the list in top position.
While excitons have been understood in theory for decades, the authors of a new Nature Communications study have directly observed these quasiparticles responsible for energy transfer in solar cells, LEDs and semiconductor circuits for the first time.

The project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.
Scientists at MIT and Harvard University have developed a light lattice that traps atoms, a technique they say could aid in the creation of powerful quantum computing systems.
For years, researchers have been interested in developing quantum computers—the theoretical next generation of technology that will outperform conventional computers.
We all learn in high school science about the dual nature of light – that it exists as both waves and quantum particles called photons.
Digital mammography screening with new photon-counting technique offers high diagnostic performance, according to a study published online, February 4, in the journal Radiology. Oak
Flying over Greenland and the Arctic Ocean in April 2012, a high-altitude aircraft completed the first polar test of a new laser-based technology designed to measure the height of Earth from space.
In contrast to its apparent simplicity (that brought Einstein his Nobel Prize), the photoelectric effect, when an electron is knocked out from its parent atom by a photon, is quite complicated to analyze in general, especially when the atom contains a large number of electrons.
Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
