Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a stream of tiny ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...
