Conspectus Molecular vibrations constitute one of the smallest mechanical oscillators
available for micro-/nanoengineering. The energy and strength of molecular oscillations …

Picocavities are sub-nanometer-scale optical cavities recently found to trap light, which are
formed by single-atom defects on metallic facets. Here, we develop simple picocavity …

Surface-enhanced Raman scattering (SERS) is typically assumed to occur at individual
molecules neglecting intermolecular vibrational coupling. Here, we show instead how …

In this paper, we address the optomechanical effects in surface-enhanced resonant Raman
scattering (SERRS) from a single molecule in a nanoparticle on mirror (NPoM) nanocavity …

Molecular vibrations and their dynamics are of outstanding importance for electronic and
thermal transport in nanoscale devices as well as for molecular catalysis. The vibrational …

The work reported in this thesis concerns how light can be coupled to plasmonic
nanocavities, increasing its electric field by orders of magnitude. Variations of a popular …

Nanocavities formed by ultrathin metallic gaps permit the reproducible engineering and
enhancement of light–matter interaction, with mode volumes reaching the smallest values …
