Faster Molecular Dynamics with Neural Network Potentials via Distilled Multiple Time-Stepping and Non-Conservative Forces
arXiv:2602.14975v3 Announce Type: replace-cross Abstract: Following our previous work (J. Phys. Chem. Lett., 2026, 17, 5, 1288-1295), we propose the DMTS-NC approach, a distilled multi-time-step (DMTS) strategy using non-conservative (NC) forces to further accelerate atomistic molecular dynamics simulations using foundation neural network models such as FeNNix-Bio1. There, a dual-level reversible reference system propagator algorithm (RESPA) formalism couples a target accurate conservative potential to a simplified distilled representation optimized for the production of non-conservative force
The accelerating development of advanced neural network models is enabling new approaches to complex scientific simulations, pushing the boundaries of computational efficiency in molecular dynamics.
This development significantly enhances the speed and fidelity of atomistic simulations, which are crucial for drug discovery, material science, and bioengineering, potentially accelerating breakthroughs in these fields.
The ability to conduct faster and more accurate molecular dynamics simulations using AI-driven methods changes the bottleneck from computational time to experimental validation or novel theoretical exploration.
