Causality of ultrafast photoionization from argon 3 s usin...

Published on 2026-06-26 by Rezvan Tahouri and Jan Marcus Dahlstrm @IOP SCIENCE

Abstract: We study real-time photoionization flux at the Amusia–Cooper minimum (ACM) in argon using ab initio simulations with the relativistic time-dependent configuration-interaction singles (RTDCIS) method in length (LG) and velocity (VG) gauges. A simple analytical model is used to interpret the results, and to construct Wigner delays and Wigner distributions for both gauges and relativistic channels of the photoelectron ( with and ). The two gauges are found to produce qualitatively different ioniz[...]


Our summary: This study investigates ultrafast photoionization in argon at the Amusia–Cooper minimum using RTDCIS simulations.
