One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

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

Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

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

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

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 study of acoustic wave scattering and diffraction in waveguide structures lies at the forefront of both theoretical and applied acoustics. It encompasses the intricate processes by which sound ...
