Raman scattering of phonon polaritons under nanoscale confinement: the role of structure and environment
George Zograf, Betul Kucukoz, Oleg Kotov +10
Strong light-matter coupling gives rise to polaritons -- quasiparticles that combine both photonic and material characteristics. Here, we show that polar nanocrystals exhibit struc…
Casimir-Lifshitz Theory for Cavity Modification of Ground-State Energy
Oleg V. Kotov, Johannes Feist, Francisco J. GarcÃa-Vidal +1
A theory for ground-state modifications of matter embedded in a Fabry-Perot cavity and whose excitations are described as harmonic oscillators is presented. Based on Lifshitz's the…
Humidity-enhanced NO gas sensing using atomically sharp edges in multilayer MoS
Abhay V. Agrawal, Alexander Yu. Polyakov, Jens Eriksson +2
Ambient humidity poses a significant challenge in the development of practical room temperature NO gas sensors. Here, we employ atomically precise zigzag edges in multilayer Mo…
Ultrathin 3R-MoS metasurfaces with atomically precise edges for efficient nonlinear nanophotonics
George Zograf, Betül Küçüköz, Alexander Yu. Polyakov +5
Dielectric metasurfaces that combine high-index materials with optical nonlinearities are widely recognized for their potential in various quantum and classical nanophotonic applic…
