"New Exotic State of Matter Discovered through Subatomic Particle Compression"

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 discovery could lead to the creation of many new types of exotic materials made from condensed matter. The researchers used a lattice of tungsten disulfide and tungsten diselenide to create the new state of matter by pushing excitons together until they were so densely packed that they could no longer move. This is the first time this new state of matter has been created in a "real" matter system, providing new insight into the behavior of bosons.

Visualizing Quantum States in 2D Materials

Scientists have developed a new approach to create separate images of individual quantum states in two-dimensional crystals of tungsten disulfide (WS2) using a technique called time-resolved momentum microscopy. By tracking the individual quantum states, researchers showed that the coupling mechanisms that lead to mixing of the states may not fully match current theories. This study provides crucial experimental support for some current theories of exciton coupling in TMDs, but also sheds light on important discrepancies.
