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…
Nonlinear semiclassical spectroscopy of ultrafast molecular polariton dynamics
Michael Reitz, Arghadip Koner, Joel Yuen-Zhou
We introduce a theoretical framework that allows for the systematic and efficient description of the ultrafast nonlinear response of molecular polaritons, i.e., hybrid light-matter…
Hidden nonlinear optical susceptibilities in linear polaritonic spectra
Arghadip Koner, Joel Yuen-Zhou
Linear spectra of molecular polaritons formed by molecules coupled to a microcavity photon mode are usually well described by classical linear optics, raising the question of w…
CUT-E as a expansion for multiscale molecular polariton dynamics
Juan B. Pérez-Sánchez, Arghadip Koner, Sricharan Raghavan-Chitra +1
Molecular polaritons arise when the collective coupling between an ensemble of molecules and an optical mode exceeds individual photon and molecular linewidths. The complexity…
