**DIPC Community Seminar**
The interaction between light and material excitations such as phonons or
molecular excitons can be enhanced by exploiting optical modes that confine
the electromagnetic field to small volumes. Plasmonic resonances due to the
collective oscillations of the free electrons of metallic nanoresonators are
particularly attractive to maximize the field confinement, as they are not
restricted by the diffraction limit. Here, we introduce the properties of
plasmonic systems, describe their coupling with material excitations and
present situations of current interest that exploit the extreme field
confinement to enhance the sensitivity of molecular spectroscopy techniques
and to reveal quantum effects. We establish a connection between the fields of
plasmonics and of quantum optomechanics and show that addressing excitons and
vibrations at the single-molecule level and with subnanometer resolution has
become possible in recent years, opening new possibilities for the control and
characterization of molecular properties.
