Survival of Floquet-Bloch States in the Presence of Scattering
(American Chemical Society, 2021-06-23)
Floquet theory has spawned many exciting possibilities for electronic structure control with light, with enormous potential for future applications. The experimental demonstration in solids, however, remains largely ...
Evidence for a Spin Acoustic Surface Plasmon from Inelastic Atom Scattering
(Nature, 2021-01-15)
Closed-shell atoms scattered from a metal surface exchange energy and momentum with surface phonons mostly via the interposed surface valence electrons, i.e., via the creation of virtual electron-hole pairs. The latter can ...
How Aromatic Are Molecular Nanorings? The Case of a Six-Porphyrin Nanoring**
(Wiley, 2021-11-02)
Large conjugated rings with persistent currents are novel promising structures in molecular-scale electronics. A six-porphyrin nanoring structure that allegedly sustained an aromatic ring current involving 78 pi electrons ...
