Ultrafast electron dynamics in multilayer graphene

The light-induced electron motion in atoms, molecules, and solids is the driving force of many phenomena in nature such as photosynthesis and photoelectron effect. While the ultrafast electron dynamics in atoms and molecules has been widely studied in recent years both experimentally and theoretically, the time-resolved measurements and simulations of electron motion in solids are still in their infancy. Here, we present a fully quantum model capable of describing the field-induced electron motion dynamics in multilayer graphene in real time and space. We demonstrate the application of our model to interpret a recent pioneering experiment measuring the ultrafast quantum dynamics in graphene by attosecond electron diffraction imaging technique.
