The Coarse Molecules Chose Their Own Internal State
Message passing replaced handpicked collective variables in a model that recovered a symmetry-breaking phase transition.
Summary
Message passing replaced handpicked collective variables in a model that recovered a symmetry-breaking phase transition.
Self-Consistent Ultra-Coarse-Graining assigns hidden molecular states from the model's own interactions through graph message passing instead of user-designed collective variables. On a four-particle test system, the method captured collective switching and reproduced a temperature-driven transition despite training at one temperature. The study is a methodological demonstration on a controlled model, not yet a general biomolecular simulator.
