Summary: The study presents a computational approach, known as collective dynamics using truncated equations (CUT-E), to explore the dynamics of molecular polaritons beyond simple quantum emitter ensemble models. The approach utilizes permutational symmetries to reduce computational cost and discovers an emergent hierarchy of timescales in these systems. Additionally, it systematically derives finite N corrections to the dynamics and demonstrates that the addition of a small number of effective molecules can account for phenomena with scaling rates. The results provide insight into the role of bright and dark states in chemical reactivity and offer a computationally efficient tool for polariton chemistry.

Summary: Reaction-rate modifications due to the strong coupling between molecular vibrations and the cavity vacuum have been investigated, but the mechanisms behind these observations are still unknown. This study extracted reaction-rate constants from evolving cavity transmission spectra, showing resonant suppression of the intracavity reaction rate for a specific alcoholysis reaction. By tuning the cavity modes to be resonant with the reactant and product vibrations, as well as cooperative modes, up to 80% suppression of the reaction rate was observed. An open quantum system model was used to interpret these results, suggesting the role of light-matter quantum coherences in modifying the vibrational distribution of reactants and highlighting the connection between chemistry and quantum science.

Summary: We theoretically demonstrate that the chemical reaction rate constant can be significantly suppressed by coupling molecular vibrations with an optical cavity, exhibiting both the collective coupling effect and the cavity frequency modification of the rate constant. When a reaction coordinate is strongly coupled to the solvent molecules, the reaction rate constant is reduced due to the dynamical caging effect. Moreover, we demonstrate that collectively coupling the solvent to the cavity can further enhance this dynamical caging effect, leading to additional suppression of the chemical kinetics.

Summary: This letter investigates the observed modification of thermal chemical rates in Fabry-Perot cavities and explains the mechanism behind the reduction in transmission coefficient and rate due to friction caused by cavity-reactor coupling. The authors evaluate the transmission coefficient and identify conditions for rate acceleration using an ab initio potential energy surface for the cis-trans isomerization of HONO.

Summary: This study develops an analytical rate theory for cavity-modified chemical kinetics based on the Pollak-Grabert-Hanggi theory, and investigates the changes in chemical kinetics under different solvent friction values. The results show that chemical kinetics is enhanced when solvent friction is weak and suppressed when solvent friction is strong. Furthermore, the changes in photon frequency have a greater impact on the rate in the weak friction limit.

Summary: The electromagnetic field in an optical cavity can modify and control chemical reactions through vibrational strong coupling, requiring a quantum description. The use of quantum transition state theory helps to explain resonant effect, collective effect, and selectivity in cavity-catalyzed reactions. Perturbative analysis of polariton normal modes supports the theoretical calculations and provides a general approach for other VSC phenomena.

Summary: This perspective focuses on the collective aspects of strongly coupled molecular systems and their dynamical response, discussing the energy transfer pathways from polariton states to other molecular states. Pump-probe spectroscopy can reveal these pathways, while analyzing the free energy structure in molecular polariton systems may offer new clues into energy flow and how strong coupling can be utilized.

Summary: Manipulating chemistry and material properties using hybrid light-matter states has attracted considerable interest in the past decade. The strong coupling phenomenon occurs in the dark and does not require real photons to induce. Vibrational strong coupling offers exciting possibilities for molecular and material science.

Summary: Recent experiments have shown that the properties of molecules can be altered inside an optical Fabry-Perot microcavity under collective vibrational strong coupling conditions, but this phenomenon is not yet well understood theoretically. By studying the effect of the cavity environment on the nonlinear optical response of the molecular subsystem, researchers have found that a strong excitation pulse to the lower hybrid light-matter state leads to significantly enhanced molecular nonlinear absorption within the cavity. This polariton-enhanced multiphoton absorption also results in an ultrashort polariton lifetime under strong illumination. The mechanism by which energy is transferred to higher vibrationally excited dark states is expected to be observed experimentally in different molecular systems and cavities.

Summary: Recent experiments show that coupling molecules inside an optical microcavity can control chemical reactivities, specifically through the mechanism of vibrational strong coupling. The modification of chemical reactivities in VSC polariton chemistry, dependent on photon frequency, can be explained by non-Markovian dynamics and the dynamic caging effect of the reaction coordinate. This study sheds light on the suppression of reaction rates for a specific cavity frequency, reminiscent of a solvent caging effect.

Summary: For a small fraction of hot CO2 molecules immersed in a liquid-phase CO2 thermal bath, forming collective vibrational strong coupling (VSC) between the C=O asymmetric stretch of CO2 molecules and a cavity mode accelerates hot-molecule relaxation. The acceleration is resonantly dependent on the cavity mode detuning, cooperatively dependent on Rabi splitting, and collectively scales with the number of hot molecules.

Summary: Polariton chemistry suggests that chemical reactions may be catalyzed by strong coupling without external illumination. An attempt to reproduce enhanced cyanate ion hydrolysis without observing changes in the reaction rate when cavity thickness is adjusted indicates challenges in realizing VSC-catalyzed reaction kinetics. This calls for broader efforts to validate claims of polariton chemistry.
