Dark excitons shed new light on matter

A team of Monash researchers have uncovered for the first time the full effects of interactions between exciton-polaritons and their associated dark excitonic reservoir. Exciton-polaritons (‘polaritons’, for short) are hybrid mixtures of light and matter that inherit the best properties of both. They form in semiconductors sandwiched between two mirrors, through which a laser is shone. “Polaritons capture useful properties ...
