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 ...

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 ...

The SACLA free-electron laser facility, where the experiment on the diffraction of ultra-short X-ray pulses on crystalline silicon samples was carried out. When we illuminate something, we usually ...
