In this comparative study we benchmark a recently developed nonadiabatic exchange-correlation potential within time-dependent density-functional theory (TDDFT) [Phys. Rev. Lett. 120, 157701 (2018)PRLTAO0031-900710.1103/PhysRevLett.120.157701] by (a) validating the transient dynamics using a numerically exact density-matrix renormalization-group approach as well as by (b) comparing the RC time, a typical linear-response quantity, to up to second-order perturbation theory results. As a test bed… Expand

Towards a description of the Kondo effect using time-dependent density-functional theory.
It is demonstrated that the zero-temperature conductance of the Anderson model can be calculated within the Landauer formalism combined with static density-functional theory and it is concluded that the suppression of the Kondo resonance must be attributed to dynamical exchange-correlation corrections.
