title: Counterion density profiles at charged flexible membranes.
abstract: Counterion distributions at charged flexible membranes are studied using analytical and simulation methods in both Poisson-Boltzmann and strong-coupling limits. The softer the membrane, the more smeared out the counterion-density profile becomes and counterions penetrate through the mean-membrane surface location, in agreement with anomalous scattering results. Repulsion between membrane charges enhances protrusions and induces short-scale membrane roughening.
