EvoMD-LLM: Learning the Language of Species Evolution in Reactive Molecular Dynamics

arXiv:2605.29394v1 Announce Type: new Abstract: While large language models (LLMs) excel at static scientific reasoning, they struggle to model the temporal structure of dynamic physical processes. We present EvoMD-LLM (Evolutionary Molecular Dynamics Large Language Model), a framework that reformulates species-level molecular dynamics as a symbolic temporal language modeling problem. Reactive MD trajectories are discretized into sequences of molecular events, where each token represents a chemical species augmented with its persistence duration, enabling standard autoregressive LLMs to learn

Why this matters
Why now

The increasing sophistication of LLMs and the demand for better modeling of dynamic scientific processes, combined with progress in discretizing complex simulations, makes this a natural evolution in AI application.

Why it’s important

This development allows LLMs to move beyond static reasoning to accurately model and predict dynamic chemical and biological processes, which has implications for drug discovery, material science, and synthetic biology.

What changes

LLMs' utility expands from text and static data to temporal and event-driven scientific simulations, enabling AI to 'learn the language' of physical evolution rather than just descriptive knowledge.
