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…
Functional differentiability in time-dependent quantum mechanics
Markus Penz, Michael Ruggenthaler
In this work we investigate the functional differentiability of the time-dependent many-body wave function and of derived quantities with respect to time-dependent potentials. For…
Quantum Electrodynamical Density-Functional Theory: Bridging Quantum Optics and Electronic-Structure Theory
Michael Ruggenthaler, Johannes Flick, Camilla Pellegrini +3
In this work we give a comprehensive derivation of an exact and numerically feasible method to perform ab-initio calculations of quantum particles interacting with a quantized elec…
