Topological Control of Polaritonic Flatbands in Anisotropic van der Waals Metasurfaces
Connor Heimig, Thomas Weber, Cristina Cruciano +9
Anisotropic van der Waals (vdW) materials exhibit direction-dependent optical and electronic properties, making them valuable for tailoring directional light-matter interactions. R…
Chiral Nonlinear Polaritonics with van der Waals Metasurfaces
Connor Heimig, Alexander A. Antonov, Dmytro Gryb +10
In the strong-coupling regime, the interaction between light and matter reaches a hybridization state where the photonic and material components are inseparably linked. Using tailo…
Ultrafast all-optical switching in nonlinear 3R-MoS van der Waals metasurfaces
Levin Seidt, Thomas Weber, Albert A. Seredin +7
Second-order nonlinear optical processes are fundamental to photonics, spectroscopy, and information technologies, with material platforms playing a pivotal role in advancing these…
Temporally symmetry-broken metasurfaces for ultrafast resonance creation and annihilation
Andreas Aigner, Thomas Possmayer, Thomas Weber +3
Active metasurfaces, compact platforms for nanoscale light manipulation, are transforming technologies like holography, quantum cryptography, and optical computing. Despite their v…
Coherent Acoustic Phonons in Plasmonic Nanoparticles: Elastic Properties and Dissipation at Low Temperatures
Hilario D. Boggiano, Thomas Possmayer, Luis Morguet +7
We studied the frequency and quality factor of mechanical plasmonic nanoresonators as a function of temperature, ranging from ambient to 4 K. Our investigation focused on individua…
