PROVIDENCE, R.I. [Brown University] — Amid the many mysteries of quantum physics, subatomic particles don’t always follow the rules of the physical world. They can exist in two places at once, pass ...

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

The quantum Cheshire cat effect draws its name from the fictional Cheshire Cat in the Alice in Wonderland story. That cat was able to disappear, leaving only its grin behind. Similarly, in a 2013 ...

Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger's cat analogy, ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

Forbes contributors publish independent expert analyses and insights. I cover the physics of nothing, everything, and the stuff in between. The new experimental measurement involved the magnetic ...

Scientists are redirecting their hunt for the universe's missing matter from minute particles to large, star-sized, near-invisible structures. For a long time, it was hypothesized that dark matter, ...

Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 times ...
