Physicists have taken a step that sounds like science fiction: they have coaxed light into behaving as a “supersolid,” a ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These ...

Topological insulators are one of the most puzzling quantum materials - a class of materials whose electrons cooperate in surprising ways to produce unexpected properties. The edges of a TI are ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...
