Optical nano cavities: a control knob for tuning photo-chemical reactions on a quantum level

Researchers at Fysikum have theoretically investigated the light activated hydrogen abstraction reaction of pyrrole in an optical nano cavity. The electronic excitation of pyrrole with UV light triggers the hydrogen detachment reaction along the NH bond. Their latest paper investigates how strong light-matter coupling of a tightly confined electromagnetic mode can be used to steer this reaction. The results suggest that the cavity can hugely influence the reaction efficiency and open up alternative reaction pathways.

The principle of strong coupling with confined light fields has … Continue Reading ››
