For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls of water in the open ocean to ghostly ripples inside atoms. What has ...

Tests in a gate-defined loop on graphene tracked a fractional charge circling back with a steady interference beat, as ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral atom in a vacuum. Now, for the first time, we have observed quantum ...

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

Ship waves, the complex patterns generated as vessels displace water, remain a subject of significant scientific and engineering interest. Traditionally described by Kelvin’s theory of ship wakes, ...
