We develop an accurate, highly efficient, and scalable random batch sum-of-Gaussians
(RBSOG) method for molecular dynamics simulations of systems with Coulomb interactions …

Quasi-2D Coulomb systems are of fundamental importance and have attracted much
attention in many areas nowadays. Their reduced symmetry gives rise to interesting …

We propose an accurate algorithm for a novel sum-of-exponentials (SOE) approximation of
kernel functions, and develop a fast algorithm for convolution quadrature based on the SOE …
