Summary: In this study, a coupled resonant system is proposed to simultaneously excite anisotropic borophene localized plasmonic and Bloch surface wave, allowing for exceptional flexibility in manipulating spectral response. A coupled oscillator model is used to quantitatively describe the observed BSW-BLP coupling, which can be flexibly tuned by adjusting the incident angle.

Summary: This study demonstrates strong coupling between surface phonon polariton (SPhP) resonances and molecular vibrations by using single quartz micropillars as mid-infrared optical resonators. The coupling strength depends on molecular concentration and reaches the strong coupling regime with only 7300 molecules, showing potential for promoting VSC sensitivity and miniaturizing VSC devices.

Summary: The interaction between light and molecular vibrations leads to hybrid light-matter states called vibrational polaritons. While single-molecule vibrational strong coupling (VSC) has shown many intriguing phenomena, it tends to be diminished in the presence of dark states in the many-molecule regime. This theoretical work proposes an alternative strategy to achieve single-molecule VSC using cavity-enhanced Raman spectroscopy (CERS), based on the physics of cavity optomechanics. Furthermore, a scheme is presented to couple a few-molecule VSC to thermodynamically drive a previously non-spontaneous uphill reaction.

Summary: The energetic positions of molecular electronic states at molecule/electrode interfaces play a crucial role in determining the transport and optoelectronic properties of molecular junctions. A study investigates electroluminescence from single-molecule junctions where the molecule is strongly coupled with the vacuum electromagnetic field in a plasmonic nanocavity. It demonstrates an improvement in the electroluminescence efficiency by selectively controlling the formation of the lowest-energy excited state through strong light-matter coupling. The research findings contribute to manipulating optoelectronic conversion in molecular junctions and provide design principles for efficient molecular optoelectronic devices.

Summary: By integrating a single quantum dot with a single gold nanorod, the strong coupling between quantum dots and plasmonic nanoparticles has been achieved, opening up a new pathway for solid-state quantum information processing. Utilizing a wedge nanogap cavity, the plasmonic electric fields were effectively confined in the nanoshell of the quantum dot, leading to the largest spectral Rabi splitting reported so far.

Summary: The study investigates the circular dichroism of SPPs and chiral J-aggregates in strong coupling regime, revealing significant Rabi splitting phenomenon. A method to calculate the dispersion relation in the chiral strong coupling system is developed, explaining extinctions and optical chirality of the hybrid states. The investigation of circular dichroism enriches the understanding of hybrid states and brings potential applications in the strong coupling system.

Summary: The study proposes a novel approach to achieve optomechanical strong coupling by coupling atomic motion to the cavity-dressed atomic resonance frequency. It shows that the scattering properties of single photons from the atom-cavity system become highly entangled with the atomic motional wave function. Additionally, the research analyzes some prominent features of optomechanical strong coupling, such as significant per-photon motional heating and mechanically-induced oscillations in time of the second-order correlation function of emitted light.

Summary: The model describes the transition to a strong coupling regime between an emitter and a surface plasmon, demonstrating that the shape of scattering spectra is determined by an interplay of two distinct mechanisms. The near-field coupling between the emitter and the plasmon mode influences energy exchange and provides exciton-induced transparency, while Fano interference between plasmon and emitter dipoles affects the spectral asymmetry inversion reported in experiments.

Summary: The study theoretically explores the influence of quantum surface effects in metal-dielectric layered nanostructures on the relaxation dynamics of a proximal two-level QE. The results reveal a clear splitting in the emission spectrum and non-Markovian relaxation dynamics of the emitter, indicating the presence of strong light-matter coupling despite nonclassical surface effects in the metal's optical response.

Summary: This study theoretically investigates the multi-mode coupling among the localized surface plasmon resonance, lattice mode in Ag nanorod array, and the resonant Fabry-Perot microcavity. The results show a huge Rabi splitting and anti-crossing behavior in the absorption spectra of the hybrid nanostructure. The coupling system can be controlled by adjusting the thickness of the microcavity. The proposed tunable multi-mode ultra-strong coupling system paves the way for various room-temperature quantum applications.

Summary: This study utilized surface-enhanced Raman scattering (SERS) signals to detect local structural changes in the metal-molecule interaction within a C60 single-molecule junction (SMJ). The analysis revealed vibration energy shifts originating from different Au-C60 interactions, indicating that the probability of SERS was enhanced depending on these local structural changes.
