A new window into the nature of the universe may be possible with a device proposed by scientists at the University of Nevada, Reno and Stanford University that would detect elusive gravity waves from the other end of the cosmos. Their paper describing the device and process was published in the prestigious physics journal Physical Review Letters. http://phys.org/news287940091.html Physics Thu, 16 May 2013 16:21:37 EST news287940091 An international team of physicists, including researchers from the Universities of York and St. Andrews, has demonstrated that chaos can beat order - at least as far as light storage is concerned. http://phys.org/news287135697.html Physics Tue, 07 May 2013 08:55:04 EST news287135697 By bouncing eye-safe laser pulses off a mirror on a hillside, researchers at the National Institute of Standards and Technology (NIST) have transferred ultraprecise time signals through open air with unprecedented precision equivalent to the "ticking" of the world's best next-generation atomic clocks. http://phys.org/news286640465.html Physics Wed, 01 May 2013 15:21:13 EST news286640465 (Phys.org)—Using a microscopic optical sensor that can be batch-fabricated on a silicon chip at low cost, researchers from the NIST Center for Nanoscale Science and Technology have measured the mechanical motion between two nanofabricated structures with a precision close to the fundamental limit imposed by quantum mechanics. http://phys.org/news267341434.html Physics Thu, 20 Sep 2012 06:30:44 EST news267341434 A long-time staple of science fiction is the tractor beam, a technology in which light is used to move massive objects – recall the tractor beam in the movie Star Wars that captured the Millennium Falcon and pulled it into the Death Star. While tractor beams of this sort remain science fiction, beams of light today are being used to mechanically manipulate atoms or tiny glass beads, with rapid progress being made to control increasingly larger objects. Those who see major roles for optomechanical systems in a host of future technologies will take heart in the latest results from a first-of-its-kind experiment. http://phys.org/news264257970.html Physics Wed, 15 Aug 2012 13:59:47 EST news264257970 (Phys.org) -- The world’s smallest three-dimensional optical cavities with the potential to generate the world’s most intense nanolaser beams have been created by a scientific team led by researchers with the DOE’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. In addition to nanolasers, these unique optical cavities with their extraordinary electromagnetic properties should be applicable to a broad range of other technologies, including LEDs, optical sensing, nonlinear optics, quantum optics and photonic integrated circuits. http://phys.org/news259986844.html Physics Wed, 27 Jun 2012 03:34:21 EST news259986844 At the high-brilliance synchrotron light source PETRA III, a team of DESY scientists headed by Dr. Ralf Röhlsberger has succeeded in making atomic nuclei transparent with the help of X-ray light. At the same time they have also discovered a new way to realize an optically controlled light switch that can be used to manipulate light with light, an important ingredient for efficient future quantum computers. http://phys.org/news247919520.html Physics Wed, 08 Feb 2012 13:00:18 EST news247919520 (PhysOrg.com) -- Research engineers at Yale University have succeeded in building a mechanical memory switch that is controlled and then read by lasers. In their paper published in Nature Nanotechnology, the team, led by professor Hong X. Tang, describe how they were able to use a laser to excite a small strand of solid silicon such that its bending properties that hold steady after the laser is turned off can be used as a memory device. http://phys.org/news238760134.html Nanotechnology Tue, 25 Oct 2011 11:50:01 EST news238760134 (PhysOrg.com) -- Solar cells, the heart of the photovoltaic industry, must be tested for mechanical strength, oxidized, annealed, purified, diffused, etched, and layered. http://phys.org/news238751898.html Technology Tue, 25 Oct 2011 09:00:05 EST news238751898 By combining advanced laser technologies in a new way, physicists at the National Institute of Standards and Technology (NIST) have generated microwave signals that are more pure and stable than those from conventional electronic sources. The apparatus could improve signal stability and resolution in radar, communications and navigation systems, and certain types of atomic clocks. http://phys.org/news228412321.html Physics Mon, 27 Jun 2011 16:52:22 EST news228412321 Light does not travel at the same speed in all directions under the effect of an electromagnetic field. Although predicted by theory, this counter-intuitive effect has for the first time been demonstrated experimentally in a gas by a French team from the Laboratoire 'Collisions Agregats Reactivite' at CNRS. The researchers measured with extreme precision, of around one billionth m/s, the difference between the light propagation speeds in one direction and in the opposite direction. These results open the way to more in-depth research aimed at improving the model that describes elementary particle interactions. Published on the 11 May 2011 in the journal Physical Review Letters, they point to novel applications in optics. http://phys.org/news224503136.html Physics Fri, 13 May 2011 11:00:14 EST news224503136 Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and his colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have moved a step closer to such a future, by developing liquid inks based on quantum dots that can be used to print devices. http://phys.org/news197224539.html Physics Thu, 01 Jul 2010 17:36:05 EST news197224539 Rainer Blatt's and Piet Schmidt's research team from the University of Innsbruck have successfully realized a single-atom laser, which shows the properties of a classical laser as well as quantum mechanical properties of the atom-photon interaction.

However, it’s difficult to control the entanglement generation process in a bulk crystal, and so scientists have been looking for a more fundamental source of entangled light. Now, they may have found a candidate: Bose-Einstein condensates. http://phys.org/news158408510.html Physics Wed, 08 Apr 2009 11:22:27 EST news158408510
