Extreme Optical Field Confinement and Enhancement in a Plasmonic Picopatch within a Nanoparticle-on-Mirror Resonator
Jinna He, Mario Zapata-Herrera, Xabier Arrieta +4
Plasmonic resonances in metallic nanogaps can confine light into nanometric regions, but reaching modes of volume nm remains challenging. We present a detailed theo…

Description of ultrastrong light-matter interaction through coupled harmonic oscillator models and their connection with cavity-QED Hamiltonians
Unai Muniain, Javier Aizpurua, Rainer Hillenbrand +2
Classical coupled harmonic oscillator models are capable of describing the optical and infrared response of nanophotonic systems where a cavity photon couples to dipolar matter exc…
