Time-dependent density-functional theory (TDDFT) describes the quantum dynamics of
interacting electronic many-body systems formally exactly and in a practical and efficient …

In the context of strong field–matter interaction, an increasing number of phenomena has
been found to be not understood within the single-active-electron approximation. For such …

We review the phenonomena which occur in multiphoton physics when the electric field of
the applied laser radiation becomes comparable with the Coulomb field strength seen by an …

The time-dependent complete-active-space self-consistent-field (TD-CASSCF) method for
the description of multielectron dynamics in intense laser fields is presented, and a …

We propose a criterion to determine the numerical degree of global (non-operator-specific)
correlation of a multiparticle quantum system and apply it to several situations, including …

We present an implementation of the time-dependent configuration-interaction singles
(TDCIS) method for treating atomic strong-field processes. In order to absorb the …

Time-dependent density-functional theory (TDDFT) extends the basic ideas of ground-state
density-functional theory (DFT) to the treatment of excitations and of more general time …

Analytical expressions are obtained for energy and angular distributions of ejected electrons
at the barrier-suppression and tunneling ionization of complex atoms and atomic ions by low …

The time-dependent multiconfiguration self-consistent-field method based on the occupation-
restricted multiple-active-space model is proposed (TD-ORMAS) for multielectron dynamics …

The time-dependent configuration interaction singles (TDCIS) method—an ab initio
electronic-structure technique with predictive character—is reformulated in terms of an …
