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

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

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, ...

Physicists in Japan have, for the first time, observed quantum interference in a beam of positronium — a short-lived atom made of an electron and its antimatter twin, the positron. The experiment ...

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 ...
