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 ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a stream of tiny ...

Diffraction theory describes how wave fields—acoustic, electromagnetic or quantum—interact with obstacles and apertures, producing characteristic patterns of scattering and interference. At its heart ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...
