dc.description.abstract
Strong confinement of electromagnetic modes enables frequent energy exchange between light and matter, potentially leading to the formation of hybrid light-matter states known as polaritons. To quantitatively understand how light influences materials, it is essential to treat light and matter on equal footing.
In this context, I provide an overview of ab initio quantum electrodynamics (QED) and illustrate its diverse applications, including the mode- and enantiomer-selective control of catalytic reactions. We discuss how strong coupling between optical and vibrational modes can modify chemical reaction rates [1–2], and we demonstrate that charge transfer in plasmonic catalysts can be enhanced by nearly a factor of seven through polaritonic effects [3].
Finally, the theoretical prediction of vibrationally induced resonances in the lasing behavior of organic molecules [4] highlights the potential of ab initio QED to drive progress on both sides of the light-matter interface.
