Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

A photon is a single particle of light, and under normal circumstances, it can’t be divided. But a photon is also not a ...

Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub. Normally, vortices ...

Photons act in freaky ways that remind us that nothing is as it seems at the smallest scales and most fundamental levels of ...

Despite the headline, this isn’t really a story about superconductivity—at least not the superconductivity that people care about, the stuff that doesn’t require exotic refrigeration to work. Instead, ...

Dark matter detection 2026: XENONnT set world-leading limits on axion-like particles and dark photons using 7.83 tonne-years ...

Large-scale quantum communication networks require both reliable quantum memories and coherent single-photon sources that can exchange quantum information efficiently. A coherent source of single ...

Using a “spooky” phenomenon of quantum physics, Caltech researchers have discovered a way to double the resolution of light microscopes. In a paper appearing in the journal Nature Communications, a ...
