Quantum Control of Many-Body Systems by the Density
S. E. B. Nielsen, M. Ruggenthaler, R. van Leeuwen
In this work we focus on a recently introduced method [1] to construct the external potential that, for a given initial state, produces a prescribed time-dependent density in a…
Existence, Uniqueness, and Construction of the Density-Potential Mapping in Time-Dependent Density-Functional Theory
Michael Ruggenthaler, Markus Penz, Robert van Leeuwen
In this work we review the mapping from densities to potentials in quantum mechanics, which is the basic building block of time-dependent density-functional theory and the Kohn-Sha…
Diagrammatic expansion for positive spectral functions beyond GW: Application to vertex corrections in the electron gas
G. Stefanucci, Y. Pavlyukh, A. -M. Uimonen +1
We present a diagrammatic approach to construct self-energy approximations within many-body perturbation theory with positive spectral properties. The method cures the problem of n…
Many-body Green's function theory for electron-phonon interactions: ground state properties of the Holstein dimer
N. Säkkinen, Y. Peng, H. Appel +1
We study ground-state properties of a two-site, two-electron Holstein model describing two molecules coupled indirectly via electron-phonon interaction by using both exact diagonal…
Compact two-electron wave function for bond dissociation and Van der Waals interactions: A natural amplitude assessment
K. J. H. Giesbertz, R. van Leeuwen
Electron correlations in molecules can be divided in short range dynamical correlations, long range Van der Waals type interactions and near degeneracy static correlations. In this…
