Laser Light Used To Cool Object To Quantum Ground State
2011-10-06 04:28:08

For the first time, researchers at the California Institute of Technology (Caltech), in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors as well as for quantum experiments that scientists have long dreamed of conducting. "We've taken a solid mechanical system–one made up of billions of...

International Panel of Scientists Point the Way Forward Photosynthesis is one of nature´s finest miracles. Through the photosynthetic process, green plants absorb sunlight in their leaves and convert the photonic energy into chemical energy that is stored as sugars in the plants´ biomass. If we can learn from nature and develop an artificial version of photosynthesis we would have an energy source that is absolutely clean and virtually inexhaustible. “Solar energy is...

Light intensified by plasmonics yields a nanoscale nonlinear optical device that can be controlled electronically Not long after the development of the first laser in 1960 scientists discovered that shining a beam through certain crystals produced light of a different color; more specifically, it produced light of exactly twice the frequency of the original. The phenomenon was dubbed second harmonic generation. The green laser pointers in use today to illustrate presentations are based...

Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems. Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a fraction of a second. But in new experiments at the Niels Bohr Institute researchers have succeeded in setting new records and...

BOSTON, Aug. 8, 2011 /PRNewswire/ -- While PV module manufacturers have made considerable progress driving down the cost of solar in the U.S., decreases in installer non-module costs have not kept pace, according to PHOTON Consulting's latest global solar supply-chain cost study, The True Cost of Solar Power: The Pressure's On. According to PHOTON Consulting, BOS costs now represent roughly 56-60% of total installer costs for a U.S. residential system, with the highest incurred costs...

The Photon photo sharing kiosk is a fun, affordable and desirable alternative to photo booths and digital rental cameras. Fredon, NJ (PRWEB) July 27, 2011 Until now, people wishing to collect and save galleries of sentimental, candid and valuable photo memories from large gatherings and events have been forced to rely on disposable cameras, digital camera rentals and photo booths -- and to wait days or weeks for the actual collections. The portable and easy-to-use Photon photo sharing kiosk...

Researchers at Columbia Engineering School have built optical nanostructures that enable them to slow photons down and fully control light dispersion. They have shown that it is possible for light (electromagnetic waves) to propagate from point A to point B without accumulating any phase, spreading through the artificial medium as if the medium is completely missing in space. This is the first time simultaneous phase and zero-index observations have been made on the chip-scale and at the...

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...
