Time-Dependent Density-Functional Theory

Density functional theory for stationary states or ensembles is a formulation of many-body theory in terms of the particle density, rhor. It is now a mature subject which has had many successful applications. Time-dependent density functional theory as a complete formalism is of more recent origin. A detailed description of time-dependent density-functional formalism is presented with emphasis on evolving applications.
