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 through solid barriers and even ...

Particles are nature’s smallest constituents, but that doesn’t mean they’re fundamental. So what is the Universe made of?

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

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 ...
