Latest Photon Stories
Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle.
Insightful new expose reveals how faster than light travel, green energy development is achievable through physics METFORD, Australia (PRWEB) February 10, 2015
Engineers have created a new micro-ring that “entangles” individual particles of light. This could be an important first step in a whole host of new technologies.
While investigating the use of semiconductor material fragments as components for quantum computing, Princeton University researchers developed a laser the size of a grain of rice.
Researchers from the Niels Bohr Institute at the University of Copenhagen have developed a method that used a trap to capture atoms along an ultra-thin glass fiber, where those atoms can be controlled. Their results have been published in the journal Physical Review Letters.
new insights into quantum physics may soon offer a solution for credit card fraud and identify theft
An unusual photon emission in X-ray data originating from space could be evidence for the existence of a dark matter particle, researchers from the Swiss Federal Institute of Technology in Lausanne (EPFL) report in a new study.
• Rising tide of omni-channel and digital revenue: 107+ percent growth • Traffic: 50+ percent of traffic coming from mobile web and apps • Mobile conversion rates double: 87+ percent growth
While sound typically travels far slower than light, engineers from the University of Minnesota have created sound that is loud enough so that slower sound waves can bend faster-moving light waves on a computer chip.
Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal — setting a speed record and making an important step toward realizing superfast light emitting diodes (LEDs) and quantum cryptography.
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...
