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

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, ...

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

Researchers at Tokyo University of Science have, for the first time, observed quantum interference in a beam of positronium — an exotic atom made of an electron and its antimatter twin, the positron.

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
