Researchers have developed OrbEvo, an equivariant graph transformer model designed to predict molecular wavefunctions in time-dependent density functional theory (TDDFT). This new approach aims to accelerate the simulation of molecular dynamics under external excitations, which is crucial for predicting properties like optical absorption and electron dynamics. OrbEvo utilizes wavefunction pooling or density matrix aggregation to learn the time evolution operator, showing accurate results on datasets derived from QM9 and MD17. AI
