SYAO: Symposium New Avenues in Molecular Alignment and Orientation

SYAO 1: New Avenues in Molecular Alignment and Orientation

Freitag, 14. März 2025, 14:30–16:30, HS 1+2

Alignment and orientation of molecules and clusters in the gas phase is a key ingredient of molecular and chemical physics, both for studying steric effects in chemical reactions and for imaging the structure and dynamics directly in the molecular frame. Time-resolved photoelectron spectroscopy in the molecular frame emerged as a promising approach for determining the ultrafast structural dynamics of small molecules. Significant progress was also made toward strong angular confinement of large and complex molecules and clusters, including their laser-field-free alignment to avoid interferences with the molecular dynamics.

Moreover, novel all-optical methods emerged to fully image the alignment dynamics of molecules and novel quantum control schemes have been developed based on molecular alignment for potential quantum simulators at ultracold temperatures.

This symposium gathers experts from experiments and theory and aims to provide an overview of recent developments in this important topic.
