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…
Reduced Density-Matrix Approach to Strong Matter-Photon Interaction
Florian Buchholz, Iris Theophilou, Soeren Ersbak Bang Nielsen +2
We present a first-principles approach to electronic many-body systems strongly coupled to cavity modes in terms of matter-photon one-body reduced density matrices. The theory is f…
Dressed-Orbital Approach to Cavity Quantum Electrodynamics and Beyond
S. E. B. Nielsen, C. Schäfer, M. Ruggenthaler +1
We present a novel representation of coupled matter-photon systems that allows the application of many-body methods developed for purely fermionic systems. We do so by rewriting th…
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…
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…
