Angular spectrum methods constitute a powerful framework for simulating wave propagation and diffraction phenomena in optical systems. By decomposing a complex wavefield into its constituent plane ...

Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

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 ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

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 ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

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 ...
