In recent decades, time-dependent density functional theory has been developed for computing excited-state properties of large-scale systems to high accuracy in

Non-adiabatic dynamics, where systems non-radiatively transition between electronic states, plays a crucial role in many photo-physical processes, such as fluor

Various quantum mechanical effects such as nonadiabatic transition, tunneling, and interference phenomena play crucial roles in chemical and biological systems.
