invited talks

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.

230. Ultrafast Imaging of Laser-controlled Non-adiabatic Dynamics in NO$_2$ from Time-resolved Photoelectron Emission

oral

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.

175. Generalized Phase Sensitivity of Molecular Bond Breaking

oral

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.

48. Bondsoftening Revisited

oral

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.

148. Laser-Induced Dissociative Recombination of Carbon Dioxide

Dr Hongtao Hu (Technische Universität Wien)

01/07/2019, 12:00

oral

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$^{+}$.

134. Ultrafast Laser-assisted Stabilization of Ionized Adenine

Dr Simone Latini (Max Planck Institute for the Structure and Dynamics of Matter)

oral

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.
