Strictly correlated electrons approach to excitation energies of dissociating molecules
Luis Cort, Soeren Ersbak Bang Nielsen, Robert van Leeuwen
In this work we consider a numerically solvable model of a two-electron diatomic molecule to study a recently proposed approximation based on the density-functional theory of so-ca…
The Generalized Kadanoff-Baym Ansatz with Initial Correlations
Daniel Karlsson, Robert van Leeuwen, Enrico Perfetto +1
Within the non-equilibrium Green's function (NEGF) formalism, the Generalized Kadanoff-Baym Ansatz (GKBA) has stood out as a computationally cheap method to investigate the dynamic…
Local Control and v-Representability of Correlated Quantum Dynamics
S. E. B. Nielsen, M. Ruggenthaler, R. van Leeuwen
We present a local control scheme to construct the external potential v that, for a given initial state, produces a prescribed time-dependent density in an interacting quantum many…
