Title:Electrostatics in inhomogeneous media
Seminar:CCMA Luncheon Seminar
Speaker:Dr. Zhenli Xu, Shanghai Jiao Tong University
Abstract:
In this talk, I will present electrostatic algorithms for inhomogeneous media developed in my group. The talk is composed of three parts. Firstly, we studied the image charge method of the Green's function problem of a dielectric sphere immersed in a medium described by the Poisson-Boltzmann equation, which has been used for multiscale reaction-field model of ionic fluids. Second, we discuss the harmonic interpolation algorithm for ionic interaction in spatially varying media and its application in simulating inhomogeneous electric double layers. Third, we present an algorithm for multiple dielectric objects used in studying like charge attraction. Monte Carlo simulation results based on these algorithms are present to demonstrate the performance of these algorithms, and to understand properties of colloid/electrolyte interfaces.
