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 ...

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

Scientists have long grappled with a fundamental question: what exactly is light? Is it a wave, flowing like ripples across water, or is it made up of tiny particles, like miniature paintballs zipping ...

Light’s dual nature, manifesting as both wave-like and particle-like behaviour, is a phenomenon known as wave-particle duality and remains one of the most perplexing mysteries in quantum mechanics.

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...
