The article by Schultze et al. investigates the delay in photoemission from neon atoms, which is typically assumed to occur instantly upon absorption of a high-energy photon. Using attosecond metrology, the authors found a small delay of 21 ± 5 attoseconds between the emission of electrons from the 2p and 2s orbitals. This delay is significant because it affects the timing of electron motion and the accuracy of atomic-scale chronoscopy, which relies on precise timing to study ultrafast processes. The study demonstrates that the delay is not due to delayed onset of streaking but rather to differences in the correlated motion of electrons. The results have implications for understanding electron correlations and improving theoretical models of many-electron dynamics. The authors also developed a method to extract the delay from attosecond streaking spectrograms, showing that the relative delay between the 2p and 2s photoelectrons is consistent with theoretical predictions. This work highlights the importance of precise timing in atomic chronoscopy and the need for more accurate many-electron models to improve the precision of timing measurements.The article by Schultze et al. investigates the delay in photoemission from neon atoms, which is typically assumed to occur instantly upon absorption of a high-energy photon.
