Simulating nonadiabatic quantum dynamics in molecular systems remains a significant computational challenge because of the complexity of coupled electronic and nuclear motion. We establish an exact correspondence between quantum dynamics and a Poisson process by interpreting the action of the Hamiltonian as a stochas...

The systematic construction of complex reaction networks from given reactants remains a fundamental challenge in computational chemistry. To address this, we introduce a fully automated and generally applicable workflow centered on integrated tempering sampling (ITS) within a nanoreactor framework. The protocol integra...

On-the-fly N${^2}$AMD (Neural network NAMD), a machine learning framework that makes on-the-fly NAMD in solids a reality, by employing an equivariant neural network to predict the system Hamiltonian, delivers excited-state energies, forces, and non-adiabatic coupling vectors at a fraction of the cost of ab initio calcu...
