New imaging technology captures movement of quantum particles with unprecedented resolution
(PHYSorg.com Physics)

Excitons-electrically neutral quasiparticles-have extraordinary properties. They exist only in semiconducting and insulating materials and can be easily accessed in two-dimensional (2D) materials just a few atoms thick, such as carbon and molybdenite. When these 2D materials are combined, they exhibit quantum properties that neither material possesses on its own.
