PEACE: Covariant learning of nonadiabatic manifolds with parity-resolved Hamiltonians

Rongzhi Gao, Shuguang Chen, Yang Zhou وآخرون · 2026

Nonadiabatic molecular dynamics provides mechanistic insight into light-driven processes and informs the design of molecules and materials for solar energy conversion, photocatalysis and photo switching. Accurately describing these processes requires a representation that respects electronic symmetry and consistently r …
