Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

One of the defining breakthroughs that set quantum physics apart from classical physics was the realization that matter behaves very differently at ...

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in multiple states at once.

An intense X-ray beam (in pink) is focused into a small spot on a single nanoscale grain of a platinum electrode (highlighted within the droplet). Diffraction interference patterns from that grain ...

Advancements in structured illumination and computational imaging are revolutionizing semiconductor wafer inspection, ...

Tokyo, Japan – One of the simplest and most beautiful naturally occurring patterns can be observed when light is shined through a pair of slightly misaligned periodic structures. This phenomenon, ...

Each dot forms from the constructive interference of X-rays passing through a crystal. The data can be used to examine the crystal's structure. Disclaimer: AAAS and EurekAlert! are not responsible for ...
