Coherent control of ionization via stabilization by resonant pulse pairs
Edvin Olofsson, Evan Lovelle Fulton, Rezvan Tahouri +3
We study the nonlinear and resonant process of two-photon ionization of atoms (He and H) in a pump-probe scheme. The pump pulse prepares the quantum system in a superposition of th…
Causality of ultrafast photoionization from argon 3s using an ab initio relativistic approach
Rezvan Tahouri, Jan Marcus Dahlström
We study real-time photoionization flux at the Amusia-Cooper minimum (ACM) in argon using \textit{ab initio} simulations with the relativistic time-dependent configuration-int…
Photoionization time delays probe electron correlations
Mingxuan Li, Huiyong Wang, Rezvan Tahouri +16
The photoelectric effect, explained by Einstein in 1905, is often regarded as a one-electron phenomenon. However, in multi-electron systems, the interaction of the escaping electro…
Spin-Polarized Photoelectrons in the Vicinity of Spectral Features
Stefanos Carlström, Rezvan Tahouri, Asimina Papoulia +4
It has been shown by Fano (1969) https://doi.org/10.1103/PhysRev.178.131 that photoionization of a cæsium atom by a laser pulse tuned to the vicinity of a Cooper minimum generates…
