Understanding excited state dynamics of polaritons made using organic molecules
Strong exciton-photon coupling exhibits the possibility to modify photophysical properties of organic molecules. This is due to the introduction of hybrid light-matter states, called polaritons, which have unique chemical, physical and optical properties. Those strongly coupled systems provide altered excited state dynamics in comparison to the bare molecule case. You will explore and learn to analyze the excited state dynamics of polaritons taking into consideration molecular centered states. Thus, probing the interaction between the delocalized polaritonic states and localized molecular centered states. You take projects within the field of polariton chemistry from the discussion stage, over all steps in the project cycle to finished manuscripts. You will also be encouraged to implement your previous research knowledge into projects. This in order to break new ground within the broad research topic of polaritonic chemistry, and also to promote your abilities to conceptually develop projects, which is of importance in a future career as an independent research leader.
