Photoexcited Polaron Dynamics in Rutile TiO 2 from First-Principles On-the-Fly Surface Hopping
Photoinduced polaron dynamics challenges the classical path approximation (CPA), which prescribes nuclear motion on a single potential-energy surface (PES). To overcome this limitation, we use ΔSCF-based on-the-fly surface hopping involving both ground- and excited-state PESs to study photoexcited polaron dynamics...
