Strong-field measurements of sub-femtosecond electronic and nuclear dynamics

Summary form only given. This paper describes several ideas on how intense laser pulses can be used to push the limits of time resolution and imaging of ultrafast electronic and nuclear dynamics. In atoms, it appears possible to time-resolve electronic dynamics at the level below 10 attoseconds. To achieve such extreme time resolution without resorting to equally short pulses, one has to use entanglement arising in correlated two-electron decay processes such as Auger or Coster-Kronig decay. The approach requires correlated measurement of the angle-resolved energy spectra of both correlated electrons in the presence of a laser pulse
