Charge-Transfer in Time-Dependent Density Functional Theory: Insights from the Asymmetric Hubbard Dimer
J. I. Fuks, N. T. Maitra
We show that an asymmetric two-fermion two-site Hubbard model illustrates the essential features of long-range charge-transfer dynamics in a real-space molecule. We apply a resonan…

Density functional theory beyond the linear regime: Validating adiabatic LDA
N. Helbig, J. I. Fuks, M. Casula +4
We present a local density approximation (LDA) for one-dimensional (1D) systems interacting via the soft-Coulomb interaction based on quantum Monte-Carlo calculations. Results for…

Charge-transfer in time-dependent density-functional theory via spin-symmetry-breaking
Johanna I. Fuks, Angel Rubio, Neepa T. Maitra
Long-range charge-transfer excitations pose a major challenge for time-dependent density functional approximations. We show that spin-symmetry-breaking offers a simple solution for…
