Electron wave packet interference in atomic inner-shell excitation

T Kaneyasu, Y Hikosaka, M Fujimoto, H Iwayama… - Physical Review Letters, 2021 - APS
We report the observation of quantum interference between electron wave packets launched
from the inner-shell 4 d orbital of the Xe atom. Using pairs of femtosecond radiation wave …

Strong-field control by reverse engineering

A Tóth, A Csehi - Physical Review A, 2021 - APS
Based on the idea of reverse engineering, we design an optimal laser pulse to control strong-
field multiphoton atomic transitions. Starting from the time-dependent Schrödinger equation …

Coincidence spectroscopy of molecular normal Auger decay by ultrashort x-ray pulses

YP Zhu, X Zhao, XJ Liu, V Kimberg, SB Zhang - Physical Review A, 2022 - APS
When a core-shell electron is ionized by coherent ultrashort x-ray pulses with varied
duration, different nuclear wave packets of a cationic molecule are formed, which can be …

Coherent xuv pulse induced resonant Auger process in the krypton atom

S Chatterjee - Journal of Physics B: Atomic, Molecular and …, 2019 - iopscience.iop.org
We theoretically investigate the resonant Auger (RA) process via multiple core-excited states
in the Kr atom in the presence of a coherent intense xuv pulse. Our results show the …

Effects of intense chirped x-ray laser on resonant Auger process through multiple core-excited states

In the context of the recent reported results indicating chirped laser induced suppression of
resonant Auger effect the author investigates the effects of chirping on the resonant Auger …

Theoretical investigation of an intense ultrashort xuv pulse-induced Auger cascade in krypton

S Chatterjee - JOSA B, 2020 - opg.optica.org
This paper theoretically investigates an Auger cascade triggered upon exposure of a Kr
atom to an intense ultrashort xuv laser. In the first step of the cascade, Auger electrons are …
