Noise from metallic surfaces -- effects of charge diffusion
arXiv:0709.1242 · doi:10.1103/PhysRevA.78.042902
Abstract
Non-local electrodynamic models are developed for describing metallic surfaces for a diffusive metal. The electric field noise at a distance z_0 from the surface is evaluated and compared with data from ion chips that show anomalous heating with a noise power decaying as z_0^{-4}. We find that high surface diffusion can account for the latter result.
