Abstract

Vibrational polaritons are hybrid light-matter states arising from the collective strong-coupling of ensembles of localized molecular vibrations and IR modes in a microcavities. Ground-state chemical reactions have been experimentally shown to be modified by vibrational polaritons. Currently available theories seem to be unable to explain these observations. We will describe our most recent progress in the understanding of this puzzle. In particular, we will highlight how cavity versions of transition-state and Marcus theories for chemical kinetics are limited in explaining the experiments. We argue that the underlying problem is the large number of molecules N that partake in the collective strong coupling, yielding an enormous ratio of dark states per polariton mode. We conclude with a potential solution to this problem, which relies on recognizing the conditions under which the many dark states can yield nontrivial chemical dynamics.
