Streaking and Wigner time delays in photoemission from atoms and surfaces
Chang-hua Zhang, Uwe Thumm
Streaked photoemission metrology allows the observation of an apparent relative time delay between the detection of photoelectrons from different initial electronic states. This re…

Attosecond probing of instantaneous AC Stark shifts in helium atoms
Feng He, Camilo Ruiz, Andreas Becker +1
Based on numerical solutions of the time-dependent Schrödinger equation for either one or two active electrons, we propose a method for observing instantaneous level shifts in an o…

Dielectric response effects in attosecond time-resolved streaked photoelectron spectra of metal surfaces
Chang-hua Zhang, Uwe Thumm
The release of conduction-band electrons from a metal surface by a sub-femtosecond extreme ultraviolet (XUV) pulse, and their propagation through the solid, provokes a dielectric r…
