Abstract
I investigate the tunneling decay rate of a polaritonic system formed by a strong coupling between a vacuum cavity mode and N metastable systems. Using a simple model potential, I find the instanton solutions controlling the low-temperature tunneling rate. The resulting rate modification due to the cavity is proportional to the mean of the second power of the light-matter coupling. No collective effect that would enhance the rates by a factor of √N is present, which is in line with the results in the thermal activation regime.
