A surprising breakthrough moment in superconducting physics has come from, of all places, a boozy office party at the National Institute for Materials Science in Tsukuba Japan, according to a recent AFP report. Researchers, lead by Yoshihiko Takano, made their discovery when they put tablets of an iron-based compound called Fe(Te,S) into alcoholic drinks at an office party a year ago. The phenomenon of superconductivity is the zero-loss flow of electricity through certain materials. When an...

Researchers discover a rare physical phenomenon at low temperatures and high magnetic fields Just in time for the 100th anniversary to commemorate the discovery of superconductivity by the Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden published their research results in the journal Physical Review B. Headed by Dr. Thomas Herrmannsdörfer, the team from the HZDR's High Magnetic Field Laboratory (HLD)...

When one cloud of gas meets another, they normally pass right through each other. But now, MIT physicists have created clouds of ultracold gases that bounce off each other like bowling balls, even though they are a million times thinner than air "” the first time that such impenetrable gases have been observed. While this experiment involved clouds of lithium atoms, cooled to near absolute zero, the findings could also help explain the behavior of similar systems such as neutron stars,...

On April 8, 2011, the scientific community will celebrate the centennial of the discovery of superconductivity"”the ability of certain materials to conduct electricity without resistance when cooled below a specific temperature. Quantum voltage standards are among the successful practical applications of superconductivity, so to mark the anniversary, the National Institute of Standards and Technology (NIST) has created an online museum highlighting important accomplishments and...

Completing the story they started by creating synthetic magnetic fields,* scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields. Reported in the journal Nature Physics,** these synthetic electric fields make each atom in a gas act, individually, as if it were a charged particle, but collectively they...

Researchers study quantum dots to increase the amount of electricity solar panels produceStudies done by Mark Lusk and colleagues at the Colorado School of Mines could significantly improve the efficiency of solar cells. Their latest work describes how the size of light-absorbing particles--quantum dots--affects the particles' ability to transfer energy to electrons to generate electricity.The results are published in the April issue of the journal ACS Nano.The advance provides evidence to...

Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this "pseudogap" has been a 20-year quest for researchers who are trying to control and improve these breakthrough materials, with the ultimate goal of finding superconductors that operate at room temperature."Our findings point to management and control of this other phase as the correct path toward...

By Jennifer Marcus, UCLA Physicists at UCLA set out to design a better transistor and ended up discovering a new way to think about the structure of space. Space is usually considered infinitely divisible "” given any two positions, there is always a position halfway between. But in a recent study aimed at developing ultra-fast transistors using graphene, researchers from the UCLA Department of Physics and Astronomy and the California NanoSystems Institute show that dividing space into...

"The nation that controls magnetism will control the universe," famed fictional detective Dick Tracy predicted back in 1935. Probably an overstatement, but there's little doubt the nation that leads the development of advanced magnetoelectronic or "spintronic" devices is going to have a serious leg-up on its Information Age competition. A smaller, faster and cheaper way to store and transfer information is the spintronic grand prize and a key to winning this prize is understanding and...
