Electric dipole response functions of even-even nuclei are calculated with the time-dependent density-functional theory in perturbative regime. For an easy implementation of the fully self-consistent calculation, the finite amplitude method which we have proposed recently is employed. This is the first fully self-consistent RPA calculation in the three-dimensional mesh representation, including high-energy regions of giant resonances.

We give an overview of the underlying concepts of time-dependent density-functional theory. The basic relations between densities, potentials and initial states, for time-dependent many-body systems are discussed. We obtain some new results concerning the invertability of response functions. Some fundamental difficulties associated with the time-dependent action principle are discussed and we show how these difficulties can be resolved by means of the Keldysh formalism.
