"Plasmon-enhanced molecular optomechanics"
Electronic excitations and vibrations of molecules can be efficiently excited and enhanced by the action of optical resonators which improve the interaction between light and matter. Among the variety of optical resonators, plasmonic cavities emerge as a special type which reduce the electromagnetic effective mode volumes down to the nanoscale, thus allowing to bring molecular spectroscopy such as fluorescence or Raman scattering to the extreme. Furthermore, atomic-scale morphological features in plasmonic cavities produce the ultimate confinement of light, setting sub-nanometric access and control of single-molecule excitations and nanoscale molecular optomechanics. To describe the interaction of light and matter at this level, quantum theoretical frameworks are needed.
