    Quantum Effects in Chemical Reactions under Polaritonic Vibrational Strong Coupling by Yang, Pei-Yun, Cao, Jianshu

    Published 2022
    “…The electromagnetic field in an optical cavity can dramatically modify and even control chemical reactivity via vibrational strong coupling (VSC). Since the typical vibration and cavity frequencies are considerably larger than thermal energy, it is essential to adopt a quantum description of cavity-catalyzed adiabatic chemical reactions. …”
