An atomistic electrodynamics model, where the NPs in terms of a macroscopic homogenous dielectric constant is replaced by an atomic representation with dielectric properties depending on the local chemical environment, successfully describes the plasmonics behavior in quantum size region. By using this model, we explored the near field fluctuation and  the origin of the SERS varying with time evolution.
