First principles approaches to strong light-matter coupling
ORAL
Abstract
In recent years, research at the interface of chemistry, material science, and quantum optics has surged, now opens new possibilities to study strong light-matter interactions at different limits [1,2]. In this new regime, correlated electron, nuclear and photon interactions have to be treated on the same quantized footing [3] and towards this overarching goal, we have introduced a general time-dependent density-functional theory.
In this talk, we review recent developments and show how collective Rabi splitting under strong light-matter coupling emerges for CO2 molecules in optical cavities. Further, we use this novel framework to study how the potential-energy surfaces (PES) of a CO bond stretching in an ensemble of Formaldehyde molecules is modified under collective strong-light matter coupling, demonstrating the novel abilities to alter and open new chemical reaction pathways as well as to create new hybrid states of light and matter in this regime [4].
