Meanwhile, Ref. 127 points out that a realistic cavity contains a distribution of cavity modes and not just k x = 0 mode (see Fig. ). When considering the full polariton dispersion the authors find a negligible effect in the VSC regime for nonadiabatic electron transfer rate for the type of model system studied in Ref. 36. Specifically, while Ref. 36 implicitly assumes that the density of states consists of three delta functions which are at the lower and upper polariton and the dark states, Ref. 127 generalizes their approach to a continuous density of states of polaritons and dark states. By doing so they find that the overall chemical reaction rate is proportional to an energy integral rather than a sum over three discrete contributions. The net cavity modification of chemical rate under such circumstances is negligible. This work also illustrates the importance of studying cavity-mediated chemical reactions beyond a single cavity mode.
