Real-Space Imaging of Thomson Charge Configurations in Superfluid Helium Nanodroplets

Predicting the lowest-energy arrangement of like charges on a sphere defines the Thomson problem, a long-standing challenge with analytical solutions only for a few small systems. We report a real-space experimental realization using superfluid helium nanodroplets, where surface-...

Topology-Controlled Photophysics of Ionized C14H10 Isomers

Abstract The optical signatures of polycyclic aromatic hydrocarbons (PAHs) are highly sensitive to their molecular geometry, charge state, and intermolecular interactions. A comparison between the linear anthracene and angular phenanthrene ions highlights how topological effects...
