"Squishing subatomic particles reveals exotic ultradense crystal state of matter"

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. This exotic state of matter, created by densely packing excitons, could lead to the discovery of new types of materials. The research provides new insights into the behavior of bosons and offers potential for creating additional bosonic materials with unique properties.
