Abstract: Placing a quantum dot close to a metal nanowire leads to drastic changes inits radiative decay behavior because of evanescent couplings to surfaceplasmons. We show how two non-Markovian effects, band-edge and retardation,could be observed in such a system. Combined with a quantum dot p-i-n junction,these effects could be readout via current-noise measurements. We also discusshow these effects can occur in similar systems with restricted geometries, likephononic cavities and photonic crystal waveguides. This work links twopreviously separate topics: surface-plasmons and current-noise measurements.
