Mean-field Theory and Computation of Electrostatics with Ionic Concentration Dependent Dielectrics.


We construct a mean-field variational model to study how the dependence of dielectric coefficient (i.e., relative permittivity) on local ionic concentrations affects the electrostatic interaction in an ionic solution near a charged surface. The electrostatic free-energy functional of ionic concentrations, which is the key object in our model, consists… (More)
