Vibrations of weakly coupled nanoparticles [PDF]
Physical Review B, 2010 The vibrations of a coupled pair of isotropic silver spheres are investigated and compared with the vibrations of the single isolated spheres. Situations of both strong coupling and also weak coupling are investigated using continuum elasticity and perturbation theory.

Modeling the vibrational couplings of nucleobases
The Journal of Chemical Physics, 2020 Vibrational spectroscopy, in particular infrared spectroscopy, has been widely used to probe the three-dimensional structures and conformational dynamics of nucleic acids. As commonly used chromophores, the C=O and C=C stretch modes in the nucleobases exhibit distinct spectral features for different base pairing and stacking configurations.

Vibrational coupling in plasmonic molecules [PDF]
Proceedings of the National Academy of Sciences, 2017 Significance In this work, we provide evidence of vibrational coupling between the constituent atoms in a plasmonic molecule mediated by coherent substrate phonons. A simple coupled harmonic oscillator model provides fundamental insight into the optomechanical selection rules for the launching of vibrational modes.

Chemistry under Vibrational Strong Coupling [PDF]
Journal of the American Chemical Society, 2021 Over the past decade, the possibility of manipulating chemistry and material properties using hybrid light-matter states has stimulated considerable interest. Hybrid light-matter states can be generated by placing molecules in an optical cavity that is resonant with a molecular transition.
