Photoelectron interferometry with spectrally shaped polychromatic infrared pulses
E. A. Boati, G. Arvidsson, M. Ammitzböll +19
Laser-assisted photoelectron interferometry is a cornerstone of attosecond science, first used to characterize attosecond pulse trains and later to study photoionization dynamics.…

Probing Wigner time delays with photoelectron interferometry: Anisotropic long-range imprint of the short-range centrifugal potential
Morgan Berkane, Camille Lévêque, Richard Taïeb +2
We consider the two-photon ionization of Hydrogen-like atoms. We find an approximate expression of the long-range phase based on an asymptotic expansion of the continuum eigenfunct…
