AdsMind: A Physics-Grounded Multi-Agent System for Self-Correcting Discovery of Adsorption Configurations on Heterogeneous Catalyst Surfaces
Summary
AdsMind is a closed-loop multi-agent framework designed to autonomously discover lowest-energy surface-adsorbate configurations for heterogeneous catalysis. This system addresses the computational bottleneck of exploring vast configurational spaces, which is typically prohibitive for ab initio calculations and challenging for open-loop large language model (LLM) agents lacking physics-grounded feedback. AdsMind integrates machine-learning force field (MLFF) relaxation feedback for self-correction, achieving 100% success on the AA20 benchmark and 98.8% on OCD-GMAE62. It significantly reduces the number of MLFF relaxations to 4.11 and 4.67 per case, respectively, representing an approximately 14-fold reduction over heuristic enumeration baselines. Density functional theory (DFT) validation confirms AdsMind preserves correct adsorption-energy signs, unlike open-loop methods.
Key takeaway
For research scientists modeling heterogeneous catalysis or developing autonomous chemistry workflows, AdsMind offers a robust solution to a critical bottleneck. You should consider integrating closed-loop, physics-grounded feedback mechanisms into your LLM-driven discovery systems. This approach significantly boosts reliability and computational efficiency, ensuring accurate identification of lowest-energy configurations and preventing qualitative errors in adsorption energy predictions, thereby accelerating DFT-informed material design.
