Hidden optical nonlinearities in linear spectra of quantum emitter arrays

Sricharan Raghavan-Chitra, Arghadip Koner, Joel Yuen-Zhou

Classical optical frameworks such as the discrete dipole approximation (DDA) assume that the linear spectrum of coupled quantum emitters can be computed solely from the linear susc…

Permutationally symmetric molecular aggregates

Sricharan Raghavan-Chitra, Arghadip Koner, Joel Yuen-Zhou

Linear optical spectra of molecular aggregates are often approximated by classical optics methods such as the discrete-dipole approximation (DDA), coherent exciton scattering (CES)…

Quantum theory of surface lattice resonances

Michael Reitz, Stephan van den Wildenberg, Arghadip Koner +2

The collective interactions of nanoparticles arranged in periodic structures give rise to high- in-plane diffractive modes known as surface lattice resonances. While these reson…

Dynamical Drexhage Effect: Amplified Emission in Time-Modulated Electromagnetic Environments

Juan Carlos Obeso Jureidini, Michael Reitz, Piper Fowler-Wright +4

We investigate the effect of nonrelativistic motion on the emission dynamics of a dipole emitter moving next to a reflecting interface. Within the formalism of macroscopic QED, we…

High-Q microresonators unveil quantum rare events

Sricharan Raghavan-Chitra, Arghadip Koner, Joel Yuen-Zhou

Classical linear optics posits that at sufficiently low intensities, light propagation in dielectric media is governed solely by their linear susceptibilities. Here, we demonstrate…

When do molecular polaritons behave like optical filters?

Kai Schwennicke, Arghadip Koner, Juan B. Pérez-Sánchez +4

This review outlines several linear optical effects featured by molecular polaritons arising in the collective strong light-matter coupling regime. Under weak laser irradiation and…
