In extreme ultraviolet spectroscopy, the photoionization process occurring in a molecule due
to the absorption of a single photon can trigger an ultrafast nuclear motion in the cation …

We report attosecond-scale probing of the laser-induced dynamics in molecules. We apply
the method of high-harmonic spectroscopy, where laser-driven recolliding electrons on …

The interplay between electronic and nuclear motions in molecules is a central concept in
molecular science. To what extent it influences attosecond photoionization delays is an …

The ultrafast structural, Jahn–Teller (JT) driven, electronic coherence mediated quantum
dynamics in the CH4+ and CD4+ cations that follows sudden ionization using an XUV …

Abstract The Jahn-Teller effect is an essential mechanism of spontaneous symmetry
breaking in molecular and solid state systems, and has far-reaching consequences in many …

We report on fully quantum electronic-nuclear dynamics following sudden ionization from
the neutral in the three lowest electronic states of the CH4+ and CD4+ cations. There is a …

The Jahn–Teller (JT) effect, as a spontaneous symmetry-breaking mechanism arising from
the coupling between electronic and nuclear degrees of freedom, is a widespread …

We derive expansion formulas up to arbitrary order in vibrational coordinates for the
tetrahedral and octahedral vibronic Hamiltonians that involve T and E states, and t and e …

An ab initio quantum dynamics study has been performed to explore the structural
rearrangement of ground state CH 4+ in subfemtosecond resolved photodynamics. The …

An ab initio molecular orbital study has been performed to explore the structural
rearrangement and dissociation of SiH 4+ radical cation at the X ̃ 2 T 2 ground electronic …
