CAMBRIDGE, Mass., Jan. 18, 2022 — Research from MIT and Kyushu University suggests that light could provide significantly improved performance to fuel cells, lithium batteries, and other devices that rely on the movement of charged atoms. The work introduces and demonstrates a way...
Ultracold Ions Tune Atomic Clockwork
BRAUNSCHWEIG, Germany, Dec. 30, 2021 — Researchers at the QUEST Institute at the Physikalisch-Technische Bundesanstalt (PTB) have cooled charged ions down to 200 μK. The team combined methods — its established laser cooling of coupled ions method, and those from quantum...
Transparent Display Shows Smooth Transitions over Broad Color Spectrum
CHANGCHUN, China, March 11, 2021 — Researchers from Jilin University developed a transparent glass display with a high white-light contrast ratio that is able to smoothly transition between a broad spectrum of color when stimulated with electricity. The technology overcomes hurdles...
Hollow Core Protects Optical Fibers from UV Light
ERLANGEN, Germany, and BRAUNSCHWEIG, Germany, July 3, 2014 — A new type of optical fiber can guide UV laser light without sustaining damage, as often happens with conventional fibers. Developed by a team from the Max Planck Institute and the Centre for Quantum Engineering and Space-Time Research (QUEST) at...
Optogenetic Switch Now Works Both Ways: On and Off
STANFORD, Calif., April 24, 2014 — Since the beginning of optogenetics, the technique has been more effective at switching neurons on than off -- but not anymore. Building from Dr. Karl Deisseroth’s discovery about a decade ago of optogenetics — in which light-activated...
Ultrabright Nanocrystals Could Image Single Proteins
BERKELEY, Calif., March 19, 2014 — The future is bright in the world of biological imaging with the recent creation of ultrabright, ultrasmall light-emitting crystals that can image single proteins.
Hot graphite shines new light on laser-driven fusion
COVENTRY and OXFORD, England – A new strongly heated graphite experiment has left an international team of researchers with some unexpected results that may reveal secrets of giant planets, white dwarfs and laser-driven fusion. In an attempt to learn more about how energy is...

COVENTRY and OXFORD, England, Dec. 14, 2012 — A new strongly heated graphite experiment has left an international team of researchers with some unexpected results that may shine new light on giant planets, white dwarfs and laser-driven fusion.
Nobel Prize in physics recognizes quantum-world experiments
STOCKHOLM – Two independent but related quantum optics methods for measuring and manipulating individual particles while preserving their quantum mechanical nature have been recognized by the Royal Swedish Academy of Sciences with the 2012 Nobel Prize in...
Quantum optics work wins physics Nobel
STOCKHOLM – Separate but related quantum optics technologies – ions in a harmonic trap and photons in a cavity – that allow the measurement and control of individual quantum systems were recognized by the Royal Swedish Academy of Sciences with the...
Quantum Optics Work Wins Physics Nobel
STOCKHOLM, Oct. 9, 2012 — Separate but related quantum optics technologies — ions in a harmonic trap and photons in a cavity — that allow the measurement and control of individual quantum systems were recognized Tuesday by the Royal Swedish Academy of Sciences...
Tunable, High-Quality E-beams for Tabletop Accelerators
BERKELEY, Calif., Aug. 23, 2011 — A simple way to tune highly stable electron beams through a wide range of energies for tabletop accelerators has been discovered by researchers in the LOASIS program at the US Department of Energy’s Lawrence Berkeley National Laboratory. The...
Two Atoms Entangled Using Microwaves
BOULDER, Colo., Aug. 15, 2011 — For the first time NIST physicists have linked the quantum properties of two separated ions by manipulating them with microwaves instead of the usual array of laser beams. The development could pave the way for miniaturized, easy-to-commercialize...
Zooming in on plumes to improve mass spectroscopy
BATON ROUGE, La. – By using a high-speed camera to study plumes created by a tunable infrared laser, researchers at Louisiana State University have revealed some of the mechanisms involved in material ablation. The plume study technique could someday result in better...
Earth’s UV Signature Revealed
BOULDER, Colo., Jan. 19, 2010 – On its way to rendezvous with a comet, the spacecraft Rosetta turned an eye toward Earth and recorded its ultraviolet signature. The information it collected may help astrobiologis...
Plasmas Made From Molecules
VANCOUVER, British Columbia, Nov. 24, 2008 -- A new technique for making ultracold plasmas out of molecules instead of trapped atoms brings scientists a big step closer to unlocking the secrets of the most abundant form of matter in the universe. A plasma, or ionized gas, can be as...
EUV Lithography Improved
CHAMPAIGN, Ill., Sept. 12, 2007 -- Light has been generated and optics damage lessened in extreme ultraviolet lithography by adding a lighter gas to plasma. The microelectronics lithography method is considered a candidate for creating a new generation of smaller, more powerful...
Laser Development Grant Disbursed
May 1, 2007 — A £5 million grant from the Engineering and Physical Sciences Research Council of Swindon, UK, will fund a cooperative effort to develop sources of protons, ions and gamma rays for medical, industrial and security applications. Scientists from...
PNNL Physicist Wins Presidential Honor
RICHLAND, Wash., July 27, 2006 -- Materials physicist Yanwen Zhang of Pacific Northwest National Laboratory received the 2005 Presidential Early Career Award for Scientists and Engineers (PECASE) yesterday -- the highest honor bestowed by the US government on outstanding scientists...
New Ion Trap May Lead to Working Quantum Computer
GAITHERSBURG, Md., July 11, 2006 -- Physicists have built a novel electromagnetic trap for ions that they said could be easily mass produced, potentially leading to ultrafast quantum computers large enough for practical use in complicated tasks such as breaking data encryption...
Ions Generate 5-nm X-Rays
Feb 1, 2004 — At JILA in Boulder, Colo., researchers have obtained x-rays as short as 5 nm by high-order harmonic generation from ions in an argon-filled fiber. The group reported its findings in the Jan. 23 issue of Physical Review Letters. In the work, the...
