Microscopic theory for a minimal oscillator model of exciton-plasmon coupling in hybrids of 2d semiconductors and metal nanoparticles
Lara Greten, Robert Salzwedel, Diana Schutsch +1
The common model to describe exciton-plasmon interaction phenomenologically is the coupled oscillator model. Originally developed for atomic systems rather than solid-state matter,…
Strong Coupling of Two-Dimensional Excitons and Plasmonic Photonic Crystals: Microscopic Theory Reveals Triplet Spectra
Lara Greten, Robert Salzwedel, Tobias Göde +5
Monolayers of transition metal dichalcogenides (TMDC) are direct-gap semiconductors with strong light-matter interactions featuring tightly bound excitons, while plasmonic crystals…
Spatial Exciton Localization at Interfaces of Metal Nanoparticles and Atomically Thin Semiconductors
Robert Salzwedel, Lara Greten, Stefan Schmidt +3
We present a self-consistent Maxwell-Bloch theory to analytically study the interaction between a nanostructure consisting of a metal nanoparticle and a monolayer of transition met…
Theory of radial oscillations in metal nanoparticles driven by optically induced electron density gradients
Robert Salzwedel, Andreas Knorr, Dominik Hoeing +2
We provide a microscopic approach to describe the onset of radial oscillation of a silver nanoparticle. Using the Heisenberg equation of motion framework, we find that the coupled…
Time-resolved single-particle x-ray scattering reveals electron-density as coherent plasmonic-nanoparticle-oscillation source
D. Hoeing, R. Salzwedel, L. Worbs +18
Dynamics of optically-excited plasmonic nanoparticles are presently understood as a series of sequential scattering events, involving thermalization processes after pulsed optical…
Strong coupling regime and hybrid quasinormal modes of a single plasmonic resonator coupled to a TMDC monolayer
Chelsea Carlson, Robert Salzwedel, Malte Selig +2
We present a rigorous photonic mode model to describe the strong coupling between a monolayer of and a single gold nanoparticle. The onset of strong coupling is quanti…
