An efficient and accurate MPI based parallel simulator for streamer discharges in three dimensions
Bo Lin, Chijie Zhuang, Zhenning Cai +2
In this paper, we propose an efficient and accurate message-passing interface (MPI)-based parallel simulator for streamer discharges in three dimensions using the fluid model. Firs…
Inchworm Monte Carlo method for open quantum systems
Zhenning Cai, Jianfeng Lu, Siyao Yang
We investigate in this work a recently proposed diagrammatic quantum Monte Carlo method --- the inchworm Monte Carlo method --- for open quantum systems. We establish its validity…
Burnett Spectral Method for the Spatially Homogeneous Boltzmann Equation
Zhenning Cai, Yuwei Fan, Yanli Wang
We develop a spectral method for the spatially homogeneous Boltzmann equation using Burnett polynomials in the basis functions. Using the sparsity of the coefficients in the expans…
Numerical Simulation of Microflows using Hermite Spectral Methods
Zhicheng Hu, Zhenning Cai, Yanli Wang
We propose a Hermite spectral method for the spatially inhomogeneous Boltzmann equation. For the inverse-power-law model, we generalize an approximate quadratic collision operator…
On discrete Wigner transforms
Zhenning Cai, Jianfeng Lu, Kevin Stubbs
In this work, we derive a discrete analog of the Wigner transform over the space for any prime and any positive integer . We show that the Wigne…
Approximation of the Boltzmann Collision Operator Based on Hermite Spectral Method
Yanli Wang, Zhenning Cai
Based on the Hermite expansion of the distribution function, we introduce a Galerkin spectral method for the spatially homogeneous Boltzmann equation with the realistic inverse-pow…
