TL;DR: The generation of intense, few-cycle laser pulses with a stable carrier envelope phase that permit the triggering and steering of microscopic motion with an ultimate precision limited only by quantum mechanical uncertainty are reported.

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: With the current ∼750-nm laser probe and ∼100-eV excitation, the transient recorder is capable of resolving atomic electron dynamics within the Bohr orbit time.

TL;DR: An attosecond pump–probe measurement of the density matrix of valence electrons in atomic krypton ions is reported, able to completely characterize the quantum mechanical electron motion and determine its degree of coherence in the specimen of the ensemble.

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.
