Data-driven particle dynamics: Structure-preserving coarse-graining for emergent behavior in non-equilibrium systems

arXiv — stat.MLTuesday, December 23, 2025 at 5:00:00 AM
  • A new framework for coarse-graining particle dynamics has been proposed, utilizing the metriplectic bracket formalism to preserve essential thermodynamic properties in non-equilibrium systems. This approach aims to effectively link short spatiotemporal scales with emergent bulk physics, addressing challenges in simulating multiscale systems.
  • The development is significant as it ensures that the coarse-grained models retain critical features such as momentum conservation and fluctuation-dissipation balance, which are vital for accurate predictions in complex dynamical systems.
  • This advancement aligns with ongoing efforts in the field of machine learning and computational physics to enhance the understanding of stochastic dynamics, as seen in various studies addressing high-dimensional equations and the learnability of dynamical systems, indicating a growing intersection between AI and physical modeling.
