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 ...

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to ...

Researchers at Brown University in the US have observed fractional excitons, a new class of quantum materials in a global first. These particles that defy traditional understanding of quantum ...

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 ...
