As physicists strive to cool atoms down to ever more frigid temperatures, they face the daunting task of developing new, reliable ways of measuring these extreme lows. Now a team of physicists has devised a thermometer that can potentially measure temperatures as low as tens of trillionths of a degree above absolute zero. Their experiment is reported in the current issue of Physical Review Letters and highlighted with a Viewpoint in the December 7 issue of Physics. http://www.physorg.com/news179428518.html Physics Mon, 07 Dec 2009 17:15:43 EST news179428518 (PhysOrg.com) -- Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways. http://www.physorg.com/news176569616.html Physics Wed, 04 Nov 2009 15:07:42 EST news176569616 (PhysOrg.com) -- What if atoms could be used to perform the functions currently the province of electronic devices? The goal of atomtronics is to do just that by creating analogues to the common items found in electronic devices. Ron Pepino, a graduate student at JILA and the University of Colorado, believes that he and his colleagues have found a way to create the atomtronic versions of diode and transistor circuits. The work of Pepino, Cooper, Anderson and Holland is described in Physical Review Letters: "Atomtronic Circuits of Diodes and Transistors." http://www.physorg.com/news174303837.html Physics Fri, 09 Oct 2009 10:44:44 EST news174303837 A Rice University-led team of physicists at seven U.S. universities has won $5 million from the Department of Defense to build a simulator capable of tackling high-temperature superconductivity, one of the most vexing mysteries of modern physics. http://www.physorg.com/news172925114.html Physics Wed, 23 Sep 2009 12:00:03 EST news172925114 An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard, scientists at the National Institute of Standards and Technology report in Physical Review Letters. http://www.physorg.com/news169227022.html Physics Tue, 11 Aug 2009 16:31:02 EST news169227022 Ohio State University researchers have developed a new strategy to overcome one of the major obstacles to a grand challenge in physics. http://www.physorg.com/news158516549.html Physics Thu, 09 Apr 2009 17:23:07 EST news158516549 (PhysOrg.com) -- `The concept of matter waves is at the heart of quantum mechanics,` Oliver Morsch tells PhysOrg.com. `At the beginning of the last century, scientists discovered that solid particles could exhibit properties of waves, such as interference and diffraction. Until then, it was assumed that only light behaved as a wave. But in the quantum world everything is basically a wave.` http://www.physorg.com/news157375449.html Physics Fri, 27 Mar 2009 12:25:06 EST news157375449 The investigation of complex materials such as high-temperature superconductors is problematic because of the presence of disorder and many competing interactions in real crystalline materials. "This makes it difficult to identify the role of specific interactions and, in particular, to decide whether repulsive interactions between electrons alone can explain high-temperature superconductivity," says Dr. Theodoulos Costi from the Institute of Solid State Research, Forschungszentrum Jülich, Germany. http://www.physorg.com/news147623041.html Physics Thu, 04 Dec 2008 14:24:01 EST news147623041
