Chemical manifestations of strong light–matter coupling have recently been a subject of
intense experimental and theoretical studies. Here we review the present status of this field …

Molecular polaritons are the optical excitations which emerge when molecular transitions
interact strongly with confined electromagnetic fields. Increasing interest in the hybrid …

Interaction between light and matter results in new quantum states whose energetics can
modify chemical kinetics. In the regime of ensemble vibrational strong coupling (VSC), a …

A fundamental question in the field of polaritonic chemistry is whether collective coupling
implies local modifications of chemical properties scaling with the ensemble size. Here we …

We apply the Kubo-Anderson stochastic theory of molecular spectral line shapes to the case
of polaritons formed in the collective strong-coupling regime. We investigate both the fast …

We analyze the effect of a strong perpendicular magnetic field on an intersubband transition
in a disordered doped quantum well strongly coupled to an optical cavity. The magnetic field …

We report quantum well mid-infrared photo-detectors operating in the strong light-matter
coupling regime. We claim that this is an ideal system to elucidate the elusive problem in …

Modern optoelectronic devices rely on cavity electrodynamics concepts for improved
performances, embedding the active medium in an optical cavity to enhance the light-matter …

Polariton-based devices require materials where light-matter coupling under ambient
conditions exceeds losses, but our current selection of such materials is limited. Here we …

In cavity quantum electrodynamics, strong light–matter coupling is normally observed
between a photon mode and a discrete optically active transition. In the present work we …
