New Polyatomic Complexes representation for atomistic systems unveiled

Researchers have developed a new learning representation for atomistic systems called Polyatomic Complexes, designed to be invariant to physical symmetries and unique. This representation, detailed in a paper submitted to arXiv, addresses challenges in molecular and material descriptor design by incorporating a graded geometric map that distinguishes enantiomers. The system is implemented with a bounded-cutoff approach for efficiency and is machine-checked using the Lean 4 programming language, also yielding stable topological features that capture global structure.
