Superconductivity theory under attack

Measurements on a superconducting material show an abrupt transition between a normal metal and a "strange" metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. "We don't ...

Ultrafast quantum simulations: A new twist to an old approach

Billions of tiny interactions occur between thousands of particles in every piece of matter in the blink of an eye. Simulating these interactions in their full dynamics was said to be elusive but has now been made possible ...

Leiden physicists image lumpy superconductor

High-temperature superconductivity is one of the big mysteries in physics. Milan Allan's research group used a Josephson Scanning Tunneling Microscope to image spatial variations of superconducting particles for the first ...

A graphene superconductor that plays more than one tune

Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a graphene device that's thinner than a human hair but has a depth of special traits. It easily switches from ...

Researcher discusses reopening the case of cold fusion

Researchers at MIT have collaborated with a team of scientists from the University of British Columbia, the University of Maryland, Lawrence Berkeley National Laboratory, and Google to conduct a multiyear investigation into ...
