A metallic nanocavity can act like an optical focusing lens to generate spatially highly confined plasmon with intense field of broad energy distribution. Such a unique excitation source can lead to many exciting new applications. I will introduce our several findings to highlight the fascinating properties of nanocavity plasmon (NCP), including plasmonic enhanced stimulating emission, coherent energy transfer in molecular chains, super-high resolution Raman images of a single molecule, and plasmon induced nonlinear electron scattering. I will also discuss the new theoretical model that describes the interaction between the molecules and the spatially highly confined plasmonic field.<br/>
