Dynamics and Transport of Light-Matter Hybrid Systems Beyond the Long-Wavelength Approximation

Coupling quantized radiation with matter enables a variety of exotic new chemical and physical phenomena. We focus on the dynamics of an ensemble of molecules and extended materials coupled to confined radiation, for which the spatial variation of the confined radiation cannot be ignored. We investigate how this spatial variation of the radiation and its coupling to molecules and materials can be leveraged to modify the properties of both matter and light. Specifically, we investigate cavity-modified exciton and charge transport as well as cavity-modified chemical dynamics. Our results indicate the importance of including many radiation modes and their spatial variation for accurately describing the dynamics of light-matter hybrid systems formed inside planar Fabry-Perot optical cavities.
