Physicists have taken a step that sounds like science fiction: they have coaxed light into behaving as a “supersolid,” a phase of matter that is at once rigid and frictionless. Instead of treating ...

Light, in its basic photon form, has been manipulated by scientists to behave like a solid. As a result, this expands the possibility of transforming other elements too and accelerates physics to a ...

Metal clusters made of thousands of atoms showed quantum interference, offering new insight into how large objects follow quantum rules.
