TL;DR: The confinement of the nonlinear interaction of light with matter to a single wave cycle is reported on and its utility for time-resolved and strong-field science is demonstrated.

TL;DR: Ultrafast metrology reveals a 20-attosecond delay between photoemission from different electronic orbitals in neon atoms and theoretical models refined with the help of attosecond timing metrology may provide insight into electron correlations and allow the setting of the zero of time in atomic-scale chronoscopy with a precision of a few attose Cond.

TL;DR: The real-time observation of this most elementary step in strong-field interactions: light-induced electron tunnelling is reported, and the process is found to deplete atomic bound states in sharp steps lasting several hundred attoseconds, suggesting a new technique, attose Cond Tunnelling, for probing short-lived, transient states of atoms or molecules with high temporal resolution.

TL;DR: It is demonstrated how the subcycle evolution of the electric field of light can be used to control the motion of bound electrons and provides evidence of its usefulness in controlling reaction dynamics.

TL;DR: The feasibility of electric signal manipulation in a dielectric is reported, opening the way to extending electronic signal processing and high-speed metrology into the petahertz (1015 hertz) domain.
