This paper introduces an improved method (RBSOG with RBL) for accelerating molecular dynamics simulations of Born-Mayer-Huggins (BMH) systems, which are commonly used to model ionic materials. The method addresses the computational bottlenecks associated with long-range Coulomb interactions and short-range forces by combining a sum-of-Gaussians (SOG) decomposition, importance sampling, and a random batch list (RBL) scheme. The results demonstrate significant speedups and reduced memory usage compared to existing methods, making large-scale simulations more feasible.
