Sophisticated electron-imaging technique reveals widespread "destruction," offering clues to how material works as a superconductor It's a basic technique learned early, maybe even before kindergarten: Pulling things apart - from toy cars to complicated electronic materials - can reveal a lot about how they work. "That's one way physicists study the things that they love; they do it by destroying them," said Séamus Davis, a physicist at the U.S. Department of Energy's (DOE)...

Lasers allow scientists to observe how electrons become entangled A Princeton researcher and his international collaborators have used lasers to peek into the complex relationship between a single electron and its environment, a breakthrough that could aid the development of quantum computers. The technique reveals how an isolated electron and its surroundings develop a relationship known as a Kondo state "“ a state of matter that is of great interest to physicists and engineers. The...

University of Maryland researchers have discovered a way to control magnetic properties of graphene that could lead to powerful new applications in magnetic storage and magnetic random access memory. The finding by a team of Maryland researchers, led by Physics Professor Michael S. Fuhrer of the UMD Center for Nanophysics and Advanced Materials is the latest of many amazing properties discovered for graphene. A honeycomb sheet of carbon atoms just one atom thick, graphene is the basic...

Finding presents a powerful new tool for nanoscale science experiments Cornell University researchers recently stretched individual molecules and watched electrons flow through them, proving that single-molecule devices can be used as powerful new tools for nanoscale science experiments. The finding, reported in the June 11 issue of the journal Science, probes the effects of strong electron interactions that can be important when shrinking electronics to their ultimate small size...

Theoretical spectroscopy and computational model reveal hidden ordered state Electrons in complex matter sometimes arrange themselves into strange patterns, which remain shrouded in mystery. Finding the organizing principles and classifying their phases is an important challenge in understanding condensed matter. One such material is URu2Si2. "URu2Si2 is a man-made compound based on uranium, which undergoes an unknown phase transition," said Kristjan Haule of the Center for Materials Theory...

Kondo effect noted in single-atom contacts of pure ferromagnets Spanish and U.S. physicists studying nanoelectronics have found that size really does matter when it comes to predicting the behavior of electrical contacts that are just one atom wide. In new research appearing this week in the journal Nature, physicists at Spain's University of Alicante and at Rice University in Houston have found that single-atom contacts made of ferromagnetic metals like iron, cobalt and nickel behave very...

Scientists at the IBM (NYSE: IBM) Almaden Research Center in San Jose, CA have forged a breakthrough in understanding an intriguing phenomenon in fundamental physics: the Kondo effect. They report their findings today in the scientific journal Nature Physics. The Kondo effect, one of the few examples in physics where many particles collectively behave as one object (a single quantum-mechanical body), has intrigued scientists around the world for decades. Now, using a technique that was...

  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
