Manipulating matter by strong coupling to vacuum fields

Science, Journal Year: 2021, Volume and Issue: 373(6551)

Published: July 9, 2021

Captivating cavities Laser technology is a familiar example of how confining light between two mirrors can tune its properties. Quantum mechanics also dictates that even without extraneous light, matter confined in cavity resonant with electronic or vibrational transitions couple vacuum electromagnetic field fluctuations. Garcia-Vidal et al. review the remarkable and still somewhat mysterious implications this “strong-coupling” regime, manifestations ranging from enhanced charge transport to site-selective chemical reactivity across range molecular solid-state materials.

It is possible to modify the chemical and physical properties of molecules, not only through modifications but also by coupling molecules strongly light. More intriguingly, strong between light even without presence a photon.

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.

Relevance of the Quadratic Diamagnetic and Self-Polarization Terms in Cavity Quantum Electrodynamics

ACS Photonics, Journal Year: 2020, Volume and Issue: 7(4), P. 975 - 990

Published: Feb. 26, 2020

Experiments at the interface of quantum optics and chemistry have revealed that strong coupling between light matter can substantially modify chemical physical properties molecules solids. While theoretical description such situations is usually based on nonrelativistic electrodynamics, which contains quadratic light–matter terms, it commonplace to disregard these terms restrict treatment purely bilinear couplings. In this work, we clarify origin substantial impact most common diamagnetic self-polarization highlight why neglecting them lead rather unphysical results. Specifically, demonstrate their relevance by showing leads loss gauge invariance, basis set dependence, disintegration (loss bound states) any system in limit, radiation ground state, an artificial dependence static dipole. Besides providing important guidance for modeling strongly coupled systems, presented results also indicate conditions under those effects might become accessible.

Tracking Polariton Relaxation with Multiscale Molecular Dynamics Simulations

The Journal of Physical Chemistry Letters, Journal Year: 2019, Volume and Issue: 10(18), P. 5476 - 5483

Published: Aug. 27, 2019

When photoactive molecules interact strongly with confined light modes in optical cavities, new hybrid light–matter states form. They are known as polaritons and correspond to coherent superpositions of excitations the cavity photon. The polariton energies thus potential energy surfaces changed respect bare molecules, such that formation is considered a promising paradigm for controlling photochemical reactions. To effectively manipulate photochemistry light, need remain polaritonic state long enough reaction on modified surface take place. understand what determines this lifetime, we have performed atomistic molecular dynamics simulations room-temperature ensembles rhodamine chromophores coupled single mode 15 fs lifetime. We investigated three popular experimental scenarios followed relaxation after optically pumping (i) lower polariton, (ii) upper or (iii) uncoupled states. results suggest lifetimes accessible limited by ultrafast photoemission due low lifetime reversible population transfer into "dark" manifold. Dark but much smaller contributions from photon, decreasing their emission rates hence increasing lifetimes. find between dark determined overlap absorption spectra. Importantly, excitation can also be transferred "upward" dark-state reservoir broad spectra chromophores, contrary common conception these processes "one-way" down polariton. Our chemistry relying taking place within manifold requires cavities sufficiently and, at same time, strong coupling strengths prevent back-transfer
