Quantum physicists discover breakthrough state of matter in ultradense crystals.

Physicists have discovered a new state of matter called a "bosonic correlated insulator," which takes the form of a highly ordered crystal of subatomic particles. The researchers created this state of matter by pushing excitons together until they were so densely packed that they could no longer move, creating a new symmetrical crystalline state with a neutral charge. This discovery could lead to the creation of many new types of exotic materials made from condensed matter.
