The prospect of modifying chemical processes by strong coupling molecules to vacuum fields is one that has generated a huge level of excitement [1]. However, concerns around the reproducibility of key experiments and a greater appreciation of the complexity of cavity-based physics have led to increasing caution in how experimental results are interpreted [2, 3].
In this talk I will argue...
In this presentation, I discuss our recent study investigating the influence of strong coupling in polariton organic light-emitting diodes using time-resolved electroluminescence studies [1]. We fabricated bottom-emitting polariton OLEDs, employing the well-established polariton TDAF molecular semiconductor between aluminium electrodes. Our analysis, based on a model of coupled rate equations,...
In the collective strong coupling regime where N molecules couple to an optical cavity mode, molecular polaritons may be regarded as quantum impurity models, where the impurity is a photon and the complex anharmonic molecular degrees of freedom serve as a bath. If this bath is large enough (N>>1), as in the case of most molecular polariton experiments, the quantum dynamics of such a system...
Metallic nanoparticles support localized surface plasmon resonances (LSPRs) characterized by strongly enhanced local electric fields which amplify physical process occurring in those volumes. These tunable resonances by virtue of modifying the shape and size of the nanoparticle, posses very small mode volumes, greatly amplifying the efficiency of light-matter interactions. We employ real-time...
The growing field of polariton chemistry calls for a deeper understanding of the role the different vibrational modes play in the system. The ability of low frequency vibrational modes to act as a reservoir of energy to facilitate off-resonant transitions is likely to be relevant in many processes. However, the non-Markovian nature of those modes make them hard to model. One way to capture...
