The full configuration interaction quantum Monte Carlo method in the lens of inexact power iteration
Jianfeng Lu, Zhe Wang
In this paper, we propose a general analysis framework for inexact power iteration, which can be used to efficiently solve high dimensional eigenvalue problems arising from quantum…
Efficient construction of tensor ring representations from sampling
Yuehaw Khoo, Jianfeng Lu, Lexing Ying
In this paper we propose an efficient method to compress a high dimensional function into a tensor ring format, based on alternating least-squares (ALS). Since the function has siz…
Detecting localized eigenstates of linear operators
Jianfeng Lu, Stefan Steinerberger
We describe a way of detecting the location of localized eigenvectors of a linear system for eigenvalues with comparatively large. We define the family of funct…
A Surface Hopping Gaussian Beam Method for High-Dimensional Transport Systems
Zhenning Cai, Jianfeng Lu
We propose a surface hopping Gaussian beam method to numerically solve a class of high frequency linear transport systems in high spatial dimensions, based on asymptotic analysis.…
Trigonometric integrators for quasilinear wave equations
Ludwig Gauckler, Jianfeng Lu, Jeremy L. Marzuola +2
Trigonometric time integrators are introduced as a class of explicit numerical methods for quasilinear wave equations. Second-order convergence for the semi-discretization in time…
