Nonlinear phenomena in time-dependent density-functional theory: What Rabi oscillations can teach us: "
Author(s): J. I. Fuks, N. Helbig, I. V. Tokatly, and A. Rubio
Through the exact solution of a two-electron singlet system interacting with a monochromatic laser we prove that all adiabatic density functionals within time-dependent density-functional theory are not able to discern between resonant and nonresonant (detuned) Rabi oscillations. This is rationalize...
