Flows Between Parallel Plates: Analytical Solutions of Regularized 13-Moment Equations for Inverse-Power-Law Models
Zhicheng Hu, Siyao Yang, Zhenning Cai
We study the structure of stationary channel flows predicted by the regularized 13-moment equations. Compared with the previous work [P. Taheri et al., Phys. Fluids, 21 (2009), 017…
Alternating Descent Method for Gauge Cooling of Complex Langevin Simulations
Xiaoyu Dong, Zhenning Cai, Yana Di
We study the gauge cooling technique for the complex Langevin method applied to the computation in lattice quantum chromodynamics. We propose a new solver of the minimization probl…
On the validity of complex Langevin method for path integral computations
Zhenning Cai, Xiaoyu Dong, Yang Kuang
The complex Langevin (CL) method is a classical numerical strategy to alleviate the numerical sign problem in the computation of lattice field theories. Mathematically, it is a sim…
Moment method as a numerical solver: Challenge from shock structure problems
Zhenning Cai
We survey a number of moment hierarchies and test their performances in computing one-dimensional shock structures. It is found that for high Mach numbers, the moment hierarchies a…
Numerical analysis for inchworm Monte Carlo method: Sign problem and error growth
Zhenning Cai, Jianfeng Lu, Siyao Yang
We consider the numerical analysis of the inchworm Monte Carlo method, which is proposed recently to tackle the numerical sign problem for open quantum systems. We focus on the gro…
