We study a model Coulomb fluid consisting of dipolar solvent molecules of finite extent which generalizes the point-like dipolar Poisson-Boltzmann model (DPB) previously introduced by Coalson and Duncan (1996 J. Phys. Chem. 100 2612) and Abrashkin et al (2007 Phys. Rev. Lett. 99 077801). We formulate a nonlocal Poisson-Boltzmann equation (NLPB) and study both linear and nonlinear dielectric response in this model for the case of a single plane geometry. Our results shed light on the relevance of nonlocal versus nonlinear effects in continuum models of material electrostatics.
我们研究了一种由有限尺寸的偶极溶剂分子组成的模型库仑流体，它推广了先前由科尔森和邓肯（1996年，《物理化学杂志》100卷，2612页）以及阿布拉什金等人（2007年，《物理评论快报》99卷，077801）引入的点状偶极泊松 - 玻尔兹曼模型（DPB）。我们建立了一个非局部泊松 - 玻尔兹曼方程（NLPB），并针对单平面几何情况研究了该模型中的线性和非线性介电响应。我们的结果揭示了在材料静电连续介质模型中，非局部效应与非线性效应的相关性。
