Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, revealing light-like particles with a strikingly high-dimensional character. By ...

The ALPS (Any Light Particle Search) experiment, which stretches a total length of 250 metres, is looking for a particularly light type of new elementary particle. Using twenty-four recycled ...

A team of physicists has coaxed a single, photon-like particle into behaving as if it lives in 37 different quantum ...

Albert Einstein was right about a shocking among of things, but not necessarily everything.

Long tubes, strong magnets, and bright lasers. Is that all it takes to entice the shyest particles in the universe to reveal themselves? Physicists working on the ALPS II experiment certainly hope so, ...

Results from KATRIN and MicroBooNE strongly disfavour a light sterile-neutrino explanation of longstanding anomalies.

New measurements from an experiment near the top of an extinct Mexican volcano have placed a stringent new limit on whether light can exceed the universe’s well-known top speed. Physicists have ...

After years of searching, scientists at the Micro Booster Neutrino Experiment (MicroBooNE) have ruled out the possibility of the existence of a sterile neutrino, a hypothetical particle that had long ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...
