Attosecond time delay in valence photoionization and photorecombination of argon: a TDLDA study

Abstract

We determine and analyze the quantum phases and time delays in photoionization and photorecombination of valence 3p and 3s electrons of argon using the Kohn-Sham local density functional approach. The time-dependent local density approximation (TDLDA) is used to account for the electron correlation. Resulting attosecond Wigner-Smith time delays show excellent agreements with two recent independent experiments on argon that measured the relative 3s-3p time delay in photoionization [Physical Review Letters {\bf 106}, 143002 (2011)] and the delay in 3p photorecombination [Physical Review Letters {\bf 112}, 153002 (2014)]

The paper has been withdrawn due to a computational error in Fig. 3
