Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...

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 ...

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 ...

The Materials Research X-Ray Diffraction (XRD) Facility at the University of Colorado Boulder provides cutting-edge capabilities for probing the structures of materials such as polymers, biological ...
