Abstract
Nanoplasmonics have the ability to confine light in sub-wavelength cavities, with recent
nano-fabrication developments allowing for the realization of nanometer and sub-nanometer
plasmonic cavities. We show that for such extremely small nano-cavities, the correlation between
the field enhancement resonance and the radiative (far-field) resonance breaks down. This dissociation
dominated the excitation and interference of higher-order modes in these nano-cavities.
We discuss and demonstrate the impact of this anomalous spectral behaviour for the strong
coupling of quantum emitters with plasmonic nano-cavities, where it is imperative to have nanosized
cavities.
