Model simulates closer control over the transport of information-carrying electrons Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper is about to be published in EPJ B´. This study, led by scientists from Zhejiang University, Hangzhou, China, and the Centre for Computational Science and Engineering at the National University of Singapore, could have implications for quantum...

Physicists at the University of California, San Diego have discovered patterns which underlie the properties of a new state of matter. In a paper published in the March 29 issue of the journal Nature, the scientists describe the emergence of “spontaneous coherence,” “spin textures” and “phase singularities” when excitons–the bound pairs of electrons and holes that determine the optical properties of semiconductors and enable them to function as...

International team that includes University of British Columbia physicists has used ultra-fast laser pulses to identify the microscopic interactions that drive high-temperature superconductivity An international team that includes University of British Columbia physicists has used ultra-fast laser pulses to identify the microscopic interactions that drive high-temperature superconductivity. In the experiment, to be outlined this Friday in the journal Science, electrons in a prototypical...

Previous world record shattered during 6-experiment pulse Researchers at Los Alamos National Laboratory's biggest magnet facility today met the grand challenge of producing magnetic fields in excess of 100 tesla while conducting six different experiments. The hundred-tesla level is roughly equivalent to 2 million times Earth's magnetic field. "This is our moon shot, we've worked toward this for a decade and a half," said Chuck Mielke, director of the Pulsed Field Facility at Los Alamos....

Scientists manufacture a cylinder which hides contents and makes them invisible to magnetic fields UAB researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using superconductor and ferromagnetic materials available on the market. The cylinder is built using high temperature superconductor material, easily refrigerated with liquid...

Atoms Caught Moving Within A Molecule

Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule. Key to the experiment, which appears in this week's issue of the journal Nature, is the researchers' use of the energy of a molecule's own electron as a kind of "flash bulb" to illuminate the molecular motion. The team used ultrafast laser pulses to knock one electron out of its natural orbit in a molecule. The electron then fell back toward the molecule scattered off...

Helmholtz-Zentrum Berlin developed a magnetic valve that novel electronic devices can be realistic In close collaboration with colleagues from Bochum and the Netherlands, researchers from the Helmholtz-Zentrum Berlin (HZB) have developed a novel, extremely-thin structure made of various magnetic materials. It is suitable as a kind of magnetic valve for data-storage units of the most recent generation and makes use of effects in the context of so-called spintronics, with which, in addition...

How long does it take an electron to form a photon? The answer would normally be: so short a time that it cannot be measured. However, the international CERN team responsible for experiment NA63 — mainly staffed by physicists from Aarhus University — has now succeeded in dragging out the process, thereby making it measurable. They achieved this by utilizing the phenomena of objects moving slower and shortening in length from Einstein´s theory of relativity, along with two...

Berkeley Lab Researchers Resolve Controversy Over Gallium Manganese Arsenide that Could Boost Spintronic Performance A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab)in collaboration with scientist from University of Notre Dame have determined the origin of the...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
