The particle-wave nature of light has fascinated researchers for more than 200 years, but a new experiment has allowed researchers to visualize it like never before. This image was taken by turning an ...

Electrons are elementary particles -- indivisible, unbreakable. But new research suggests the electron's quantum state -- the electron wave function -- can be separated into many parts. That has some ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...

Electron beam oscillators utilising surface wave structures represent a key technology in the generation of high‐power electromagnetic radiation. By deploying relativistic electron beams in ...

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 ...

Albert Einstein was awarded the Nobel Prize in Physics in 1921 for his work on the wave-particle behavior of light, helping explain the photoelectric effect and spurring further development of quantum ...

You've likely read in a textbook before that light behaves both as a particle and a wave at the same time. Scientists had previously seen it behave one way or another, but it's only now that someone ...

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 ...

Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...

Antimatter isn't just made of antiparticles, it's also made of waves. Now we know that this holds true even at the level of a single antimatter particle. Physicists have known for a long time that ...
