First Experimental Signs of a New Physics Beyond the Standard Model
July 31, 2013 — Physicists have predicted deviations in the probability of one of the B meson decays that have been detected experimentally in the LHC accelerator at CERN. Confirmation of these results would be the ... > full story -
Cause of LED 'Efficiency Droop' Identified
July 30, 2013 — Researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called "efficiency droop" that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to ... > full story -
Experimental Quest to Test Einstein's Speed Limit
July 29, 2013 — Special relativity states that the speed of light is the same in all frames of reference and that nothing can exceed that limit. UC Berkeley physicists used a novel experimental system -- the unusual ... > full story -
Largest Magnetic Fields in the Universe
July 26, 2013 — Numerical simulations show for the first time the occurrence of an instability in the interior of neutron stars that can lead to gigantic magnetic fields, possibly triggering one of the most dramatic ... > full story -
Behavior of Turbulent Flow of Superfluids Is Opposite That of Ordinary Fluids
July 25, 2013 — A superfluid moves like a completely frictionless liquid, seemingly able to propel itself without any hindrance from gravity or surface tension. The physics underlying these materials -- which appear ... > full story -
What If Quantum Physics Worked on a Macroscopic Level? Researchers Have Successfully Entangled Optic Fibers Populated by 500 Photons
July 25, 2013 — Quantum physics concerns a world of infinitely small things. But for years, researchers have been attempting to observe the properties of quantum physics on a larger scale, even ... > full story -
Elementary Physics in a Single Molecule
July 25, 2013 — Physicists have succeeded in performing an extraordinary experiment: They demonstrated how magnetism that generally manifests itself by a force between two magnetized objects acts within a single ... > full story -
The Ferromagnetic Kondo Effect: A Circuit Simulates an Effect Predicted by Physicists but Never Actually Observed
July 24, 2013 — A group of physicists has shown how to obtain a particular case of a physical effect -- so far never observed in reality -- whose studies have earned a Nobel Prize. The scientists have also observed ... > full story -
Mirror, Mirror on the Wall, Who Has the Lowest Noise of Them All
July 21, 2013 — Scientists have demonstrated a novel "crystalline coating" technique for producing low-loss mirrors. This technology will further accelerate progress in the development of narrow-line width ... > full story -
Making Big 'Schroedinger Cats': Quantum Research Pushes Boundary by Testing Micro Theory for Macro Objects
July 21, 2013 — Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday ... > full story
