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 ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed ...

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 ...
