Trajectory-based solution of the nonadiabatic quantum dynamics equations: an on-the-fly approach for molecular dynamics simulations.

The non-relativistic quantum dynamics of nuclei and electrons is solved within the framework of quantum hydrodynamics using the adiabatic representation of the electronic states. An on-the-fly trajectory-based nonadiabatic molecular dynamics algorithm is derived, which is also able to capture nuclear quantum effects that are missing in the traditional trajectory surface hopping approach based o...

Nonadiabatic Molecular Dynamics Based on Trajectories

Performing molecular dynamics in electronically excited states requires the inclusion of nonadiabatic effects to properly describe phenomena beyond the Born-Oppenheimer approximation. This article provides a survey of selected nonadiabatic methods based on quantum or classical trajectories. Among these techniques, trajectory surface hopping constitutes an interesting compromise between accuracy...

Large nonadiabatic quantum molecular dynamics simulations on parallel computers

We have implemented a quantummolecular dynamics simulation incorporating nonadiabatic electronic transitions onmassively parallel computers to study photoexcitation dynamics of electrons and ions. The nonadiabatic quantum molecular dynamics (NAQMD) simulation is based on Casida’s linear response time-dependent density functional theory to describe electronic excited states and Tully’s fewestswi...

Ab initio multiple cloning algorithm for quantum nonadiabatic molecular dynamics.

We present a new algorithm for ab initio quantum nonadiabatic molecular dynamics that combines the best features of ab initio Multiple Spawning (AIMS) and Multiconfigurational Ehrenfest (MCE) methods. In this new method, ab initio multiple cloning (AIMC), the individual trajectory basis functions (TBFs) follow Ehrenfest equations of motion (as in MCE). However, the basis set is expanded (as in ...

Nonadiabatic Car-Parrinello molecular dynamics.

An extension of Car-Parrinello (CP) molecular dynamics for efficient treatment of electronically nonadiabatic processes is presented. The current approach couples the S1 restricted open-shell Kohn-Sham excited state to the S0 ground state using a surface hopping scheme. Efficient evaluation of the nonadiabatic couplings is achieved by exploiting the available wave function time derivatives. Sin...
