(Color online) Radial dependence of the induced electric density ρ(r/a)|l=0 for the monotonic (red broken line) and non-monotonic (blue solid line) steps shown in Fig. 1. The density is normalized by the value of the point charge in the center of the sphere. The inset magnifies a small, oscillatory feature associated with the nonmonotonic step.
