Chemistry under Vibrational Strong Coupling

Journal of the American Chemical Society, Journal Year: 2021, Volume and Issue: 143(41), P. 16877 - 16889

Published: Oct. 5, 2021

Over the past decade, possibility of manipulating chemistry and material properties using hybrid light-matter states has stimulated considerable interest. Hybrid can be generated by placing molecules in an optical cavity that is resonant with a molecular transition. Importantly, hybridization occurs even dark because coupling process involves zero-point fluctuations mode (a.k.a. vacuum field) In other words, unlike photochemistry, no real photon required to induce this strong phenomenon. Strong general, but vibrational (VSC) particular, offers exciting possibilities for and, more generally, science. Not only it new tool control chemical reactivity, also gives insight into which vibrations are involved reaction. This Perspective underlying fundamentals coupling, including mini-tutorial on practical issues achieve VSC. Recent advancements "vibro-polaritonic chemistry" related topics presented along challenges field.

Published: Aug. 8, 2023

When molecules are coupled to an optical cavity, new light-matter hybrid states, so-called polaritons, formed due quantum interactions. With the experimental demonstrations of modifying chemical reactivities by forming polaritons under strong interactions, theorists have been encouraged develop methods simulate these systems and discover strategies tune control reactions. This review summarizes some exciting theoretical advances in polariton chemistry, ranging from fundamental framework computational techniques applications spanning photochemistry vibrational coupling. Even though theory interactions goes back midtwentieth century, gaps knowledge molecular electrodynamics (QED) only recently filled. We recent made resolving gauge ambiguities, correct form different QED Hamiltonians gauges, their connections various optics models. Then, we developed ab initio approaches which can accurately describe states a realistic molecule-cavity system. then discuss using method advancements. advancements where cavity is resonant electronic transitions nonadiabatic excited state dynamics enable photochemical reactivities. resonance tuned vibrations instead, ground-state reaction modifications demonstrated experimentally, its mechanistic principle remains unclear. present progress this mystery. Finally, understanding collective coupling regime between light matter, many collectively couple single mode or modes. also lay out current challenges explain observed results. hope that will serve as useful document for anyone who wants become familiar with context chemistry thus significantly benefit entire community.

Published: Dec. 19, 2022

Strong light-matter interaction in cavity environments is emerging as a promising approach to control chemical reactions non-intrusive and efficient manner. The underlying mechanism that distinguishes between steering, accelerating, or decelerating reaction has, however, remained unclear, hampering progress this frontier area of research. We leverage quantum-electrodynamical density-functional theory unveil the microscopic behind experimentally observed reduced rate under induced resonant vibrational strong coupling. observe multiple resonances obtain thus far theoretically elusive but critical feature for single strongly coupled molecule undergoing reaction. While we describe only mode do not explicitly account collective coupling intermolecular interactions, qualitative agreement with experimental measurements suggests our conclusions can be largely abstracted towards realization. Specifically, find acts mediator different modes. In effect, energy localized bonds are redistributed differently which ultimately inhibits
