Weyl fermions possess exotic properties and can act like magnetic monopoles. Researchers show that TaAs is a Weyl semimetal, demonstrating for the first time that Weyl semimetals can be identified experimentally.

The surface states of topological insulators are protected from backscattering, making them a promising resource for computing and materials science. This topological protection is now demonstrated in a radio-frequency circuit.

Robert Laughlin is back with a vengeance. After a decade away from physics, the Nobel laureate at Stanford University in Palo Alto, California, argues in a pair of soon-to-be published papers that most physicists' basic assumptions about the origins of high-temperature superconductivity--the ability of certain materials to carry electricity without resistance at still frigid, but unusually high temperatures--are wrong. Instead, Laughlin argues, the biggest mystery in condensed matter physics can be explained starting from the conventional theory of metals, a tack most theorists abandoned decades ago. Laughlin has spent recent years writing popular science books and had a turbulent tenure from 2004 to 2006 as the president of the Korea Advanced Institute of Science and Technology in Daejeon. He declined to answer questions about his papers, which are in press at Physical Review Letters and Physical Review B, saying they ...

Information theory was originally developed to study the fundamental limits of telecommunication. But thanks to recent extensions it can now also be applied to solid-state physics.

Calculations predicting a new high-pressure superconductor are borne out by experiment.
