Polaritonic chemistry exploits strong light–matter coupling between molecules and confined
electromagnetic field modes to enable new chemical reactivities. In systems displaying this …

In the past decade, much theoretical research has focused on studying the strong coupling
between organic molecules (or quantum emitters, in general) and light modes. The …

We analyze how the photorelaxation dynamics of a molecule can be controlled by modifying
its electromagnetic environment using a nanocavity mode. In particular, we consider the …

Cavity-mediated light–matter coupling can dramatically alter opto-electronic and physico-
chemical properties of a molecule. Ab initio theoretical predictions of these systems need to …

Light-induced nonadiabatic phenomena arise when molecules or molecular ensembles are
exposed to resonant external electromagnetic fields. The latter can either be classical laser …

Polaritons–hybrid light-matter states formed in cavity–strongly change the properties of the
underlying matter. In optical or plasmonic nanocavities, polaritons decay by radiative …

The interaction of a molecule with the quantized electromagnetic field of a nanocavity gives
rise to light-induced conical intersections between polaritonic potential energy surfaces. We …

Strong coupling of molecules with quantized electromagnetic fields can reshape their
potential energy surfaces by forming dressed states. In such a scenario, it is possible to …

Plexcitonic strong coupling has ushered in an era of room‐temperature quantum
electrodynamics at the nanoscale. Realizing its potential applications from single‐molecule …

Simulating photon dynamics in strong light–matter coupling situations via classical
trajectories is proving to be powerful and practical. Here, we analyze the performance of the …
