Ultrafast electron-nuclear dynamics can nowadays be accessed using attosecond XUV/IR pump-probe protocols. Recent accurate theoretical simulations describing the sub-femtosecond dynamics triggered in ionized diatomic and polyatomic molecules are presented.
We show that time-/energy-resolved anisotropy parameters of photoelectron angular distributions provide a clear mapping of both the ultrafast natural dynamics at the conical intersection of NO$_2$ and its modifications induced by an ultrashort control pulse.
We investigated the relation between the intrinsic and CEP-induced asymmetries in laser-induced bond-breaking of H$_{2}$. We show that the intrinsic asymmetry is modulated by the CEP via the variation of the field-strength at the ionization-time.
We reveal an unexpected facet of bond softening in H$_2$, namely a strikingly structured angular distribution of emitted protons. The angular modulations arise from rich dynamics in a light-induced potential landscape, which we track experimentally.
Using multi-body coincidence measurements, we studied laser-induced dissociative recombination of CO$_{2}$ after strong field double ionization. We observed the localization of the recombined Rydberg electron dominantly on O$^{+}$ rather than CO$^{+}$.
A NIR pulse following attosecond XUV-photoionization at specific time delay can prevent irreparable damage of adenine. We identify the stabilizing mechanism in electronic correlation driven charge migration away from the molecular plane.
