Diagrammatic approach to attosecond delays in photoionization
J. M. Dahlström, T. Carette, E. Lindroth
We study laser-assisted photoionization by attosecond pulses using a time-independent formalism based on diagrammatic many-body perturbation theory. Our aim is to provide an ab ini…
Introduction to attosecond time-delays in photoionization
J. M. Dahlström, A. L'Huillier, A. Maquet
This tutorial presents an introduction to the interaction of light and matter on the attosecond timescale. Our aim is to detail the theoretical description of ultra-short time-dela…
Photoemission time-delay measurements and calculations close to the 3s ionization minimum in Ar
D. Guenot, K. Klunder, C. L. Arnold +12
We present experimental measurements and theoretical calculations of photoionization time delays from the and shells in Ar in the photon energy range of 32-42 eV. The exp…
Theory of attosecond delays in laser-assisted photoionization
J. M. Dahlström, D. Guénot, K. Klünder +5
We study the temporal aspects of laser-assisted extreme ultraviolet (XUV) photoionization using attosecond pulses of harmonic radiation. The aim of this paper is to establish the g…
