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 ...

The study of acoustic wave scattering and diffraction in waveguide structures lies at the forefront of both theoretical and applied acoustics. It encompasses the intricate processes by which sound ...

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 ...

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 ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...
