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.

Physics is simple. In fact, it never ceases to astonish me how, with a few simple ideas from physics in your suitcase, you can travel from your own backyard to the most exotic realms of the universe, ...

Physicists in Leiden have recreated Thomas Young’s iconic double-slit experiment using gigahertz sound waves on gallium arsenide, revealing both parallels and differences with light. The study found ...

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 ...
