Quantum physicists simulate Dirac equation, 1 of the cornerstones in physics Researchers of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, used a calcium ion to simulate a relativistic quantum particle, demonstrating a phenomenon that has not been directly observable so far: the Zitterbewegung. They have published their findings in the current issue of the journal Nature. In the 1920s quantum mechanics was already established and in 1928 the British...

DARPA to provide funding to quell Casimir force Scientists at the U.S. Department of Energy's Argonne National Laboratory are developing a way to control the Casimir force, a quantum mechanical force, which attracts objects when they are only hundred nanometers apart. "The Casimir force is so small that most experimentation has dealt simply with its characteristics," said Derrick Mancini, interim director of the Center for Nanoscale Materials. "If we can control this force or make it...

Research team discovers a new use for metamaterials that promises to eliminate mechanical friction in nanotechnology Nanoscale machines expected to have wide application in industry, energy, medicine and other fields may someday operate far more efficiently thanks to important theoretical discoveries concerning the manipulation of famous Casimir forces that took place at the U.S. Department of Energy's Ames Laboratory. The groundbreaking research, conducted through mathematical simulations,...

Achieving an important new capability in ultracold atomic gases, researchers at the Joint Quantum Institute, a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have created "synthetic" magnetic fields for ultracold gas atoms, in effect "tricking" neutral atoms into acting as if they are electrically charged particles subjected to a real magnetic field. The demonstration, described in the latest issue of the journal Nature, not only...

Information field theory enables astronomers, medical practitioners and geologists to look into places where their measuring instruments are blind A bit of imagination on the part of a measuring instrument wouldn't be a bad thing. It could help to add data from areas where the instrument is unable to measure. However, it must do so constructively. In order to infer missing data in an astronomical measurement with more than just imagination, physicists at the Max Planck Institute for...

BETHLEHEM, Pa., Nov. 10 /PRNewswire/ -- Particle Sciences Inc., a leading pharmaceutical CRO, has further expanded their capabilities by the acquisition of additional space bringing their total to approximately 21,000 sq ft. "Our current workload and existing pipeline simply necessitates this addition," says Dr. Mark Mitchnick, CEO. "2009 has been a record year for us and we have pretty good visibility on the next 12 months. The additional space will be used to expand our cGMP warehouse...

Researchers have unearthed a magnetic force similar to electricity: magnetic charges that act and interrelate like electrical charges. This is the first known use of the magnetic monopoles that subsist in spin ice crystals. A research team wrote that monopoles have the ability to group together and form a "magnetic current" similar to electricity. Called "magnetricity", this new discovery may be utilized in magnetic storage or computers. Magnetic monopoles were first thought to be present a...

Any child can tell you that a magnet has a "north" and a "south" pole, and that if you break it into two pieces, you invariably get two smaller magnets with two poles of their own. But scientists have spent the better part of the last eight decades trying to find, in essence, a magnet with only one pole. A team working at the National Institute of Standards and Technology (NIST) has found one.* In 1931, Paul Dirac, one of the rock stars of the physics world, made the somewhat startling...

Nuclear magnetic moment is one of the most important physical observables. The precise measurement of nuclear magnetic moment and its understanding in microscopic way are quite a challenge in nuclear physics. The research team at Peking University, who has dedicated to the study of nuclear structure and astrophysics for the last decades, has applied the configuration-fixed deformation constrained RMF approach with time-odd component to investigate the ground-state properties of 33Mg and...

Researchers from the Helmholtz-Zentrum Berlin fr Materialien und Energie have, in cooperation with colleagues from Dresden, St. Andrews, La Plata and Oxford, for the first time observed magnetic monopoles and how they emerge in a real material. They publish this result in the journal Science within the Science Express web site on Sept. 3. Magnetic monopoles are hypothetical particles proposed by physicists that carry a single magnetic pole, either a magnetic North pole or South pole. In the...

Communications in Mathematical Physics is a peer-reviewed academic journal published by Springer. The founding editor-in-chief was Rudolf Haag, who established the journal in 1965 with the help of Res Jost. Haag headed the journal for the next eight years, and was succeeded by Klaus Hepp, followed by James Glimm, Arthur Jaffe and the Michael Aizenman, who took over in 2000. The journal publishes papers in all fields of mathematical physics, but focuses particularly in analysis related to...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
