A class of glass that cannot crystallize, even given infinite time, is forcing physicists to rethink some of the oldest assumptions about how disordered materials behave. Built from theoretical models ...

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — must be incomplete, because there are a host of phenomena it cannot ...

For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the ...

Artist’s conception of the mystery of the magnetic moment of the muon—a sub-atomic particle similar to, but heavier than, an electron (represented by the Greek letter mu). More than half a century of ...
