Scientists Capture Elusive Quantum Floquet States With Visible Light

Researchers have directly observed Floquet states in semiconductors using all-optical spectroscopy under ambient conditions, revealing new possibilities for controlling chemical reactions with light. Solution-processed semiconductor nanocrystals, known as colloidal quantum dots (QDs), are an example of size-dependent quantum effects that physicists had long understood in theory. However, it wasn’t until the discovery of QDs that […]
