  The spontaneous emission rate of dipole emitters close to plasmonic dimers
are theoretically studied within a nonlocal hydrodynamic model. A nonlocal
model has to be used since quantum emitters in the immediate environment of a
metallic nanoparticle probe its electronic structure. Compared to local
calculations, the emission rate is significantly reduced. The influence is
mostly pronounced if the emitter is located close to sharp edges. We suggest to
use quantum emitters to test nonlocal effects in experimentally feasible
configurations.
