When photoactive molecules interact strongly with confined light modes, new hybrid light-matter states may form: the polaritons. These polaritons are coherent superpositions of excitations of the molecules and of the cavity photon. Recently, polaritons were shown to mediate energy transfer between chromophores at distances beyond the Förster limit. Here we explore the potential of strong coupling for light-harvesting applications by means of atomistic molecular dynamics simulations of mixtures of photoreactive and non-photo-reactive molecules strongly coupled to a single confined light mode. These molecules are spatially separated and present at different concentrations. Our simulations suggest that while the excitation is initially fully delocalized over all molecules and the confined light mode, it very rapidly localizes onto one of the photoreactive molecules, which then undergoes the reaction.

Thermal disorder prevents the suppression of ultra-fast photochemistry in the strong light-matter coupling regime
Dutta, Arpan; Tiainen, Ville; Sokolovskii, Ilia; Duarte, Luís; Markešević, Nemanja; Morozov, Dmitry; Qureshi, Hassan A.; Pikker, Siim; Groenhof, Gerrit; Toppari, J. Jussi (Nature Publishing Group, 2024)Strong coupling between molecules and confined light modes of optical cavities to form polaritons can alter photochemistry, but the origin of this effect remains largely unknown. While theoretical models suggest a suppression ... -
Photochemical initiation of polariton-mediated exciton propagation
Sokolovskii, Ilia; Groenhof, Gerrit (De Gruyter, 2024)Placing a material inside an optical cavity can enhance transport of excitation energy by hybridizing excitons with confined light modes into polaritons, which have a dispersion that provides these light–matter quasi-particles ... -

Jussi (American Chemical Society, 2019)When photoactive molecules interact strongly with confined light modes in optical cavities, new hybrid light-matter states form.

Multi-scale molecular dynamics simulations of enhanced energy transfer in organic molecules under strong coupling
Sokolovskii, Ilia; Tichauer, Ruth H.; Morozov, Dmitry; Feist, Johannes; Groenhof, Gerrit (Springer, 2023)Exciton transport can be enhanced in the strong coupling regime where excitons hybridize with confined light modes to form polaritons. Because polaritons have group velocity, their propagation should be ballistic and ... -
Reinforcing strong coupling with hybrid microcavities for polariton chemistry application
Qureshi, Hassan Ali (2021)The light-matter coupling is a physical phenomenon in which optical modes of light are in resonance with the energy level of matter, thus enabling exchange of energy between them. The strong light-matter coupling is achieved ...
