Physics and Matter News - May 2009 Archives
While the perils associated with particle physics, from Earth-gobbling black holes to Vatican-destroying amounts of antimatter, gain news headlines, it's easy to overlook the large economic and societal benefits of particle physics research.

 | A team of physicists and engineers have demonstrated all-fiber quantum logic, where single photons are generated and used to perform the controlled-NOT quantum logic gate in optical fibers with high fidelity. ...> Full Article |
On May 26, Nanyang Technological University's School of Biological Science will pioneer the world's first remotely controlled Solution X-Ray Scattering experiment. The experiment will be initiated from Singapore at 4.10pm - 6pm in SBS and conducted at the German Electron Synchrotron, Hamburg, Germany.

 | Berkeley Lab researchers have demonstrated that electric fields can be used as ON/OFF switches in multiferroic materials, a development that holds promise for future magnetic data storage and spintronic devices. ...> Full Article |
Kansas State University theorists have developed a model that allows them to compute not just the energy of photo-emitted electrons, but also the times after their release at which they can be detected. Within their quantum mechanical model, they found that electrons that are emitted by ultra-short laser pulses from different parts of a metal surface will arrive at an electron detector at slightly different times.

 | Researchers have created a new type of invisibility cloak that is simpler than previous designs and works for all colors of the visible spectrum, making it possible to cloak larger objects than before and possibly leading to practical applications in "transformation optics." ...> Full Article |
 | Breakthrough research that yielded the world's first-ever ship degaussing system to use high temperature superconducting (HTS) materials garnered "Top Navy Scientist and Engineer of the Year" accolades for George Stimak, a program officer at the US Office of Naval Research. ...> Full Article |
Scientists are a step closer to making environmentally-friendly 'magnetic' refrigerators and air conditioning systems a reality, thanks to new research published today in Advanced Materials.

Researchers in condensed matter physics at the University of Pennsylvania and the University of Chicago have created an experimental and computer model to study how jamming, the physical process in which collections of particles are crammed together to behave as solids, might affect the behavior of systems in which thermal motion is important, such as molecules in a glass.

Since Galileo Galilei and Newton, the assumption is valid that inert and heavy mass are equivalent. This is, however, questioned by new physical theories such as the string theory. Now, the equivalence principle is put to test with so far unachieved accuracy within the scope of the "microscope" space project -- a German-French cooperation. PTB has developed the manufacturing and measuring methods for the test masses.

Scientists at the California Institute of Technology have developed an efficient method to detect entanglement shared among multiple parts of an optical system. They show how entanglement, in the form of beams of light simultaneously propagating along four distinct paths, can be detected with a small number of measurements. Entanglement is an essential resource in quantum information science, which is the study of advanced computation and communication based on the laws of quantum mechanics.

 | A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off. ...> Full Article |
Experts from around the globe will be converging on Des Moines May 12-15 to discuss the state of the art of magnetic refrigeration. Scientists and industry representatives will be attending the Third International Conference on Magnetic Refrigeration, Thermag III, which is being hosted by the US Department of Energy's Ames Laboratory and Iowa State University.

James Shaffer, professor in the OU Department of Physics, was part of the German-led team that made the recent discovery that some say demonstrates a "new" type of bonding, which makes this molecule different from other Rydberg molecules. The electron scattering in this approach can be used as a benchmark test for future quantum calculations of atomic and molecular structure.
