Summary: The study explores the strong coupling between surface plasmons and molecular excitons, where an additional anti-crossing feature may arise at high oscillator strengths, but the physics behind this double anti-crossing feature is still unclear. Extensive transfer matrix simulations reveal different anti-crossing features between surface plasmons and excitonic resonances at different oscillator strengths.

By tracing the roots of the corresponding dispersion relations in the complex frequency plane, it is shown that electronic and vibrational polaritons are natural eigenstates of resonant materials that require no external cavity.

Summary: In vibrational strong coupling, the interaction between molecular vibrations and optical cavity modes can modify the kinetics of thermally activated chemical reactions. Dissipative processes introduced by VSC can accelerate internal thermalization, ultimately suppressing nonequilibrium effects in reactions outside the cavity. This phenomenon is mainly attributed to cavity decay and plays a supporting role by relaxation between polaritons and dark states.

Summary: Recent experiments have shown that the properties of molecules can be altered inside an optical Fabry-Perot microcavity under collective vibrational strong coupling conditions, but this phenomenon is not yet well understood theoretically. By studying the effect of the cavity environment on the nonlinear optical response of the molecular subsystem, researchers have found that a strong excitation pulse to the lower hybrid light-matter state leads to significantly enhanced molecular nonlinear absorption within the cavity. This polariton-enhanced multiphoton absorption also results in an ultrashort polariton lifetime under strong illumination. The mechanism by which energy is transferred to higher vibrationally excited dark states is expected to be observed experimentally in different molecular systems and cavities.

Summary: This study investigates the elastic response of a system where a cavity field is strongly coupled with molecular excitons, revealing the failure of the commonly used coupled oscillator model due to non-Lorentzian dissipation. Results show that the polariton response varies depending on temperature, molecular Stokes shift and vibration frequencies, as well as the size of the Rabi splitting. The findings can serve as a check for experiments aiming to prove results originating from strong coupling.

Summary: The theoretical study explores second-harmonic generation in plasmonic nanostructures interacting with two-level quantum emitters under incoherent energy pump. Strong QE-SPP coupling leads to orders of magnitude enhancement in SHG efficiency, which is further supported by simulations showing increased SHG efficiency when QEs are tuned to resonance with lattice plasmon mode. Enhancement of SHG efficiency is also demonstrated by tuning QEs to localized plasmon mode and utilizing strong local electric fields. The polarization dependence of SHG is examined in relation to the symmetries of participating plasmon modes.

Summary: Coupling molecules to the confined light modes of an optical cavity shows promise for manipulating chemical reactions, but a complete understanding of the effects of strong light-matter coupling on molecular dynamics and reactivity is needed to fully exploit this principle.

Summary: The vibrational strong coupling of molecules to optical cavities based on plasmonic resonances has been explored recently due to the ability of plasmonic near-fields to provide strong coupling in sub-diffraction limited volumes. This work demonstrates an angle-independent plasmonic nanodisk substrate that overcomes limitations of traditional optical cavities and allows for strong coupling with all molecules on the surface, regardless of molecular orientation. The large linewidths of the plasmon resonance enable simultaneous strong coupling to two orthogonal water vibrational modes, with the Rabi splitting varying as a function of plasmon frequency and strong coupling achieved for a range of diameters.

Summary: Researchers have successfully described the coupled cavity-single molecule interactions in the weak-to-strong-coupling regimes by generalizing quantum-electrodynamical density functional theory to account for dissipative dynamics of the cavity. By tuning the coupling, cavity-mediated energy transfer between electronically excited states has been achieved. This generalized ab initio quantum-electrodynamical density functional theory treatment can be extended to describe cavity-mediated interactions in arbitrary electromagnetic environments, bridging the gap between electronic structure theory, quantum optics, and nanophotonics.

Summary: The study utilizes Quantum Electrodynamics Coupled-Cluster (QED-CC) theory to model the changes in ground-state properties of a series of sodium halide compounds strongly coupled to an optical cavity. It shows that electron affinities (EAs) are significantly affected by cavity interactions, while ionization potentials (IPs) are less sensitive to the presence of the cavity. The predicted EAs by QED-CC theory can be reduced by up to 0.22 eV when considering experimentally accessible coupling parameters.

Summary: The interaction between the enhanced electromagnetic field of a confined light mode and photoactive molecules can lead to the formation of new hybrid light-matter states known as polaritons. These polaritons, as evidenced by the Rabi split in the dispersion, have the potential to control the chemistry of the coupled molecules. Experimental and molecular dynamics simulation results indicate that the molecular Stokes shift plays a significant role in the relaxation of polaritons formed by organic molecules within metallic Fabry-Perot cavities embedded in a polymer matrix. Moreover, it was observed that the mechanism of energy transfer from the fluorescing state of a non-strongly coupled molecule to the lower polariton involves non-adiabatic couplings between uncoupled molecules and the polaritons.

Experimental characterization of plexciton systems usually involves comparing scattering, absorption, or luminescence spectra, while theoretical interpretations vary from classical to quantum-mechanical frameworks.

Summary: This study evaluates the impact of strongly coupling cavity photons on the excited state dynamics of zinc (II) tetraphenyl porphyrin and copper (II) tetraphenyl porphyrin molecules, finding different mechanisms leading to the localization of polaritonic states. A simple kinetic model for zinc (II) tetraphenyl porphyrin includes a direct channel of relaxation between polaritonic states, while strong cavity coupling slows internal conversion between electronic states of copper (II) tetraphenyl porphyrin. Researchers must consider vibrational structure and excited state properties of strongly coupled chromophores when using polariton formation to control molecule dynamics.
