Enhancement of the WS A Raman Mode in MoS/WS Heterostructures
Annika Bergmann-Iwe, Tomasz Woźniak, Tomasz Woźniak +11
When combined into van der Waals heterostructures, transition metal dichalcogenide monolayers enable the exploration of novel physics beyond their unique individual properties. How…
Ultrastrong Light-Matter Coupling in Materials
Niclas S. Mueller, Eduardo B. Barros, Stephanie Reich
Ultrastrong light-matter coupling has traditionally been studied in optical cavities, where it occurs when the light-matter coupling strength reaches a significant fraction of the…
THz-Driven Coherent Phonon Fingerprints of Hidden Symmetry Breaking in 2D Layered Hybrid Perovskites
Joanna M. Urban, Michael S. Spencer, Maximilian Frenzel +10
Metal-halide perovskites (MHPs) emerged as a family of novel semiconductors with outstanding optoelectronic properties for applications in photovoltaics and light emission. Recentl…
Nanocavities for Molecular Optomechanics: their fundamental description and applications
Philippe Roelli, Huatian Hu, Ewold Verhagen +2
Vibrational Raman scattering -- a process where light exchanges energy with a molecular vibration through inelastic scattering -- is most fundamentally described in a quantum frame…
Double tips for in-plane polarized near-field microscopy and spectroscopy
Patryk Kusch, Jose Pareja Arcos, Aleksei Tsarapkin +4
Near-field optical microscopy and spectroscopy provide high-resolution imaging below the diffraction limit, crucial in physics, chemistry, and biology for studying molecules, nanop…
