A discrete energy level of an atomic vacancy in an atomically thin material shifts upon excitation of a drum-like vibration. The temporal evolution of the localized energy level is intricately linked to the atomic excursions owing to the drum mode. Credit: Brad Baxley Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second. Throwing a ball into the air, one can transfer arbitrary ...
