Molecular Chemistry in Cavity Strong Coupling

Chemical Reviews, Journal Year: 2023, Volume and Issue: 123(13), P. 8099 - 8126

Published: June 30, 2023

The coherent exchange of energy between materials and optical fields leads to strong light-matter interactions so-called polaritonic states with intriguing properties, halfway light matter. Two decades ago, research on these interactions, using cavity (vacuum) fields, remained for the most part province physicist, a focus inorganic requiring cryogenic temperatures carefully fabricated, high-quality cavities their study. This review explores history recent acceleration interest in application molecular properties processes. enormous collective oscillator strength dense films organic molecules, aggregates, allows vacuum field coupling be achieved at room temperature, even rapidly highly lossy metallic cavities. has put associated phenomena fingertips laboratory chemists, scientists, biochemists as potentially new tool control chemistry. exciting that have emerged suggest are genuine relevance within material landscape.

Impact of Dipole Self-Energy on Cavity-Induced Nonadiabatic Dynamics

Journal of Chemical Theory and Computation, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

The coupling of matter to the quantized electromagnetic field a plasmonic or optical cavity can be harnessed modify and control chemical physical properties molecules. In cavities, term known as dipole self-energy (DSE) appears in Hamiltonian ensure gauge invariance. aim this work is twofold. First, we introduce method, which has its own merits complements existing methods, compute DSE. Second, study impact DSE on cavity-induced nonadiabatic dynamics realistic system. For that purpose, various matrix elements are computed functions nuclear coordinates system after laser excitation investigated. induce conical intersections between polaritons, gives rise substantial effects. shown slightly affect these light-induced and, particular, break their symmetry.

Manipulating azobenzene photoisomerization through strong light–molecule coupling

Nature Communications, Journal Year: 2018, Volume and Issue: 9(1)

Published: Nov. 2, 2018

Abstract The formation of hybrid light–molecule states (polaritons) offers a new strategy to manipulate the photochemistry molecules. To fully exploit its potential, one needs build toolbox polaritonic phenomenologies that supplement those standard photochemistry. By means state-of-the-art computational approach extended strong-coupling regime, here we disclose various mechanisms peculiar chemistry: coherent population oscillations between polaritons, quenching by trapping in dead-end and alteration photochemical reaction pathway quantum yields. We focus on azobenzene photoisomerization, encompasses essential features complex reactions such as presence conical intersections coordinates involving multiple internal modes. In strong coupling intersection arises characterize role process. Our chemically detailed simulations provide framework rationalize how impacts realistic
