Physicists discover quantum particles that break the rules of reality
Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in a one-dimensional system. Even more exciting, these strange particles may be adjustable, allowing scientists to tune their behavior in ways never before possible.

Physicists have traditionally sorted all elementary particles in our three-dimensional universe into two categories: bosons and fermions. Bosons mostly include particles that carry forces, such as photons, while fermions make up ordinary matter, including electrons, protons, and neutrons.
That simple division starts to break down in lower dimensional systems. Since the 1970s, scientists have predicted the existence of a third type of particle known as an anyon, which falls somewhere…
