Optical current generation in graphene: CEP control vs. ω + 2ω control
The injection of directional currents in solids with strong optical fields has attracted
tremendous attention as a route to realize ultrafast electronics based on the quantum-
mechanical nature of electrons at femto-to attosecond timescales. Such currents are usually
the result of an asymmetric population distribution imprinted by the temporal symmetry of the
driving field. Here we compare two experimental schemes that allow control over the
amplitude and direction of light-field-driven currents excited in graphene. Both schemes rely …
