In the realm of vibrational strong coupling, where the exchange of photons between molecular vibrations and cavity radiation modes outpaces any decay processes, recent experiments in Fabry-Pérot cavities have reported rate modifications in ground-state chemical reactions under resonant conditions. These findings have catalyzed the emergence of a vibrant new field of research known as polariton chemistry, prompting further experimental inquiries into a broad spectrum of chemical reactions within microfluidic infrared optical cavities and spurring substantial theoretical investigations. This burgeoning field not only provides a fresh new avenue for comprehending chemical reaction mechanisms at a fundamental level but also presents a novel technique for selectively steering chemical reactions in an inexpensive and non-intrusive manner. Such advancements hold the potential for profound impacts on both chemical and material science.
