Theoretical analysis of time delays and streaking effects in XUV photoionization
Jing Su, Hongcheng Ni, Andreas Becker +1
We apply a recently proposed theoretical concept and numerical approach to obtain time delays in extreme ultraviolet (XUV) photoionization of an electron in a short- or long-range…
Numerical simulation of time delays in light induced ionization
Jing Su, Hongcheng Ni, Andreas Becker +1
We apply a fundamental definition of time delay, as the difference between the time a particle spends within a finite region of a potential and the time a free particle spends in t…
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…
