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 ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

Diffraction phenomena are of fundamental importance for the characterization and analysis of materials in industrial and scientific applications. Prominent examples include X-ray crystallography as ...

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...
