Abstract
This paper demonstrates real-space and real-time imaging of quantum electronic coherences in molecules using a combination of scanning tunneling microscopy (STM) and attosecond laser pulses. By employing carrier-envelope-phase (CEP)-stable near-infrared laser pulses, the researchers visualize coherences involving the valence orbitals of perylenetetracarboxylic dianhydride (PTCDA) molecules with ångström-scale spatial and subfemtosecond temporal resolutions. The study shows full control over the population of involved orbitals, paving the way for observing and manipulating electron dynamics in complex molecular systems.
