Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom. A ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...

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 ...

Light microscopy is the only way in which we can look inside a living cell, or living tissues, in three dimensions. An electron microscope only gives a two-dimensional view, and the organic sample ...

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 ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

Researchers at the Technion-Israel Institute of Technology have measured “dark points” inside light waves that appear to travel faster than light itself, confirming a theoretical prediction made half ...

Surface plasmons are collective oscillations of free electrons that occur at the interface between a metal and a dielectric medium, such as air or glass. These oscillations are coupled with ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
