This is achieved by employing a local atomic basis-set representation and real-time propagation of excited state wave functions. We implement the method within SIESTA, a standard ground-state DFT package with local atomic basis, and demonstrate its potential for realistic and accurate excited state dynamics simulations using small and medium-sized molecules as examples (H-2, CO, O-3, and indolequinone). The method can be readily applied to problems involving nanostructures and large biomolecules.en-USJournal Article2019-09-2010.1063/1.2960628
