(Phys.org)—Researchers from the University of Southampton have called in to question a 40 year-old theory explaining the periodic speeding up or 'glitching' of pulsars. http://phys.org/news275050837.html Space & Earth Tue, 18 Dec 2012 11:00:48 EST news275050837 (Phys.org)—A group of physicists from Japan have taken to the skies to grow crystals under zero gravity. http://phys.org/news274554767.html Physics Wed, 12 Dec 2012 19:00:02 EST news274554767 (Phys.org)—Physicists working at the Institute for Quantum Electronics in Switzerland have succeeded in building an apparatus that has allowed for the observation of the drop of resistance in the flow of a superfluid Fermi gas. They describe their work in a paper they've had published in the journal Nature. http://phys.org/news273399689.html Physics Thu, 29 Nov 2012 09:10:01 EST news273399689 (Phys.org)—A mathematician at the University of Glasgow is helping to find an answer to one of the last unsolved problems in classical mechanics. http://phys.org/news272187007.html Physics Thu, 15 Nov 2012 07:30:15 EST news272187007 (PhysOrg.com) -- A series of neutron scattering experiments at Oak Ridge National Laboratory and other research centers is exploring the key question about a long-sought quantum state of matter called supersolidity: Does it exist? http://phys.org/news247479850.html Physics Fri, 03 Feb 2012 09:10:01 EST news247479850 Every time you boil water in a kettle, you witness a phenomenon known as a phase transition — water transforms from a liquid to a gas, as you can see from the bubbling water and hissing steam. MIT physicists have now observed a much more elusive phase transition: that from a gas into a superfluid, a state where particles flow without any friction. http://phys.org/news246086492.html Physics Wed, 18 Jan 2012 05:21:47 EST news246086492 (PhysOrg.com) -- A Cambridge team have built a semiconductor chip that converts electrons into a quantum state that emits light but is large enough to see by eye. Because their quantum superfluid is simply set up by shining laser beams on the device, it can lead to practical ultrasensitive detectors.  Their research is published today, 08 January in Nature Physics. http://phys.org/news245317266.html Physics Mon, 09 Jan 2012 07:41:16 EST news245317266 (PhysOrg.com) -- It has been 100 years since the discovery of superconductivity, a state achieved when mercury was cooled, with the help of liquid helium, to nearly the coldest temperature achievable to form a superfluid that provides no resistance to electrons as they flow through it. http://phys.org/news226846446.html Physics Thu, 09 Jun 2011 14:00:24 EST news226846446 (PhysOrg.com) -- NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in laboratories on Earth exhibit remarkable properties, such as the ability to climb upward and escape airtight containers. The finding has important implications for understanding nuclear interactions in matter at the highest known densities. http://phys.org/news217689715.html Space & Earth Wed, 23 Feb 2011 13:22:21 EST news217689715 (PhysOrg.com) -- In Swinburne University's 'cold molecules lab', where temperatures one millionth of a degree above absolute zero are routinely achieved, researchers are making significant advances in understanding the weird and wonderful world of quantum mechanics. http://phys.org/news202624318.html Physics Thu, 02 Sep 2010 05:34:07 EST news202624318 New experiments are casting doubt on previously reported observations of supersolid helium. In a paper appearing in the current issue of Physical Review Letters, John Reppy (Cornell University) presents research suggesting that prior experiments that seemed to show signs of supersolidity were in fact the result of the plastic deformation of normal helium. http://phys.org/news196344359.html Physics Mon, 21 Jun 2010 13:20:01 EST news196344359 (PhysOrg.com) -- When helium is cooled to around 4 degrees above absolute zero, it turns liquid. Make it a couple of degrees cooler, and it becomes a "superfluid" that flows without resistance from its container, just as electrons flow without resistance in a superconductor. http://phys.org/news160408487.html Physics Fri, 01 May 2009 14:55:07 EST news160408487 (Physorg.com) -- If physicists lived in Flatland—the fictional two-dimensional world invented by Edwin Abbott in his 1884 novel—some of their quantum physics experiments would turn out differently (not just thinner) than those in our world. The distinction has taken another step from speculative fiction to real-world puzzle with a paper* from the Joint Quantum Institute (JQI) reporting on a Flatland arrangement of ultracold gas atoms. The new results, which don’t quite jibe with earlier Flatland experiments in Paris, might help clarify a strange property: “superfluidity.” http://phys.org/news157206744.html Physics Wed, 25 Mar 2009 13:33:30 EST news157206744 Physicists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology and the University of Maryland have proposed a recipe for turning ultracold “boson” atoms—the ingredients of Bose-Einstein condensates—into a “supersolid,” an exotic state of matter that behaves simultaneously as a solid and a friction-free superfluid. While scientists have found evidence for supersolids in complex liquid helium mixtures, a supersolid formed from such weakly interacting gas atoms would be simpler to understand, potentially providing clues for making a host of new “quantum materials” whose bizarre properties could expand physicists’ notions of what is possible with matter. http://phys.org/news151090051.html Physics Tue, 13 Jan 2009 17:27:31 EST news151090051
