Random Batch Method with Momentum Correction
Yanshun Zhao, Jingrun Chen, Zhiwen Zhang
The Random Batch Method (RBM) is an effective technique to reduce the computational complexity when solving certain stochastic differential problems (SDEs) involving interacting pa…
A QMC-deep learning method for diffusivity estimation in random domains
Liyao Lyu, Zhiwen Zhang, Jingrun Chen
Exciton diffusion plays a vital role in the function of many organic semiconducting opto-electronic devices, where an accurate description requires precise control of heterojunctio…
Efficient multiscale methods for the semiclassical Schrödinger equation with time-dependent potentials
Jingrun Chen, Sijing Li, Zhiwen Zhang
The semiclassical Schrödinger equation with time-dependent potentials is an important model to study electron dynamics under external controls in the mean-field picture. In this pa…
A multiscale reduced basis method for Schrödinger equation with multiscale and random potentials
Jingrun Chen, Dingjiong Ma, Zhiwen Zhang
The semiclassical Schrödinger equation with multiscale and random potentials often appears when studying electron dynamics in heterogeneous quantum systems. As time evolves, the wa…
Two-parameter asymptotic expansions for elliptic equations with small geometric perturbation and high contrast ratio
Jingrun Chen, Ling Lin, Zhiwen Zhang +1
We consider the asymptotic solutions of an interface problem corresponding to an elliptic partial differential equation with Dirich- let boundary condition and transmission conditi…
