Modifying the energy landscape of existing molecular emitters is an attractive challenge with
favourable outcomes in chemistry and organic optoelectronic research. It has recently been …

We study the dependence of the vacuum Rabi splitting (VRS) on frequency disorder,
vibrations, near-field effects, and density in molecular polaritonics. In the mesoscopic limit …

Hybridisation of the cavity modes and the excitons to polariton states together with the
coupling to the vibrational modes determine the linear optical properties of organic …

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 light–matter interactions significantly modify the optical properties of molecules in the
vicinity of plasmonic metal nanoparticles. Since the dimension of the plasmonic cavity …

The following thesis investigates energy transfer and transport processes in the presence of
strong light-matter interactions. The matter counterpart is made up of ensembles of near-field …
