This part considers the underlying theory and practical aspects of time-dependent density functional theory (TDDFT) and time-dependent Hartree–Fock (TDHF), including:
The foundations of these theories
The linear response formulation of TDDFT/TDHF, most commonly used to calculated excited states
Various aspects of excited state calculations, including:
The challenge of charge transfer (CT) states
This is currently being worked on, and a thorough discussion on single-reference methods can be found here.
