An Iterative Method for Problems with Multiscale Conductivity [PDF]

Computational and Mathematical Methods in Medicine, 2012
A model with its conductivity varying highly across a very thin layer will be considered. It is related to a stable phantom model, which is invented to generate a certain apparent conductivity inside a region surrounded by a thin cylinder with holes. The thin cylinder is an insulator and both inside and outside the thin cylinderare filled with the same

Multiscale discontinuous Petrov–Galerkin method for the multiscale elliptic problems [PDF]

Numerical Methods for Partial Differential Equations, 2017
In this article, we present a new multiscale discontinuous Petrov–Galerkin method (MsDPGM) for multiscale elliptic problems. This method utilizes the classical oversampling multiscale basis in the framework of a Petrov–Galerkin version of the discontinuous Galerkin method, allowing us to better cope with multiscale features in the solution.

A Multiscale Finite Element Method for the Schrödinger Equation with Multiscale Potentials [PDF]

SIAM Journal on Scientific Computing, 2019
In recent years, an increasing attention has been paid to quantum heterostructures with tailored functionalities, such as heterojunctions and quantum matematerials, in which quantum dynamics of electrons can be described by the Schrödinger equation with multiscale potentials.
