Selective Ultrafast Excitation and Dephasing of Gap Plasmons into Hot Carriers in Structural Color Generation

Abstract Plasmon-induced hot-carriers generated through Landau damping underpin applications in plasmonic optoelectronics, energy conversion, and photocatalysis. However, it remains unclear whether these carriers retain the spatial localization of their parent plasmon modes or ra...

Chirality Unlocks Sub‐Terahertz Molecular Dynamics In Peptide Nanotubes

Low-frequency modes in the picosecond range play a key role in molecular recognition and biomolecular function. Here, we investigate how these dynamics at the interfaces of self-assembled peptide biomaterials relate to fine structural details of the supramolecular assembly. We re...
