Title: Effect of dark states on cavity-modified photochemistry
Plain: When many molecules couple to light in a cavity, only a few hybrid states carry the light while most states, called dark states, look like ordinary molecules. It is unclear whether photochemistry can be changed when nearly all excitations end up in dark states.
Precise: For $N$ organic emitters under electronic strong coupling with a cavity mode, with reorganization energy $\lambda$ and static energetic disorder $\sigma$, compute the photoreaction quantum yield (for example photoisomerization) after excitation of the lower polariton, accounting for relaxation into the $N-1$ dark states. The answer is whether, and in what range of $\lambda$, $\sigma$ and Rabi splitting, the yield differs from the cavity-free value by more than 10 percent.
Settled by: Large-N simulations of polariton relaxation and reaction dynamics validated against cavity photoisomerization experiments.
