Casimir Self-Interaction Energy Density of Quantum Electrodynamic Fields
Alexandre Tkatchenko, Dmitry V. Fedorov
Quantum electrodynamic fields possess fluctuations corresponding to transient particle/antiparticle dipoles, which can be characterized by a non-vanishing polarizability density. H…
Optimized Quantum Drude Oscillators for Atomic and Molecular Response Properties
Szabolcs Góger, Almaz Khabibrakhmanov, Ornella Vaccarelli +2
The quantum Drude oscillator (QDO) is an efficient yet accurate coarse-grained approach that has been widely used to model electronic and optical response properties of atoms and m…
Comprehensive Quantum Framework for Describing Retarded and Non-Retarded Molecular Interactions in External Electric Fields
Mohammad Reza Karimpour, Dmitry V. Fedorov, Alexandre Tkatchenko
We employ various quantum-mechanical approaches for studying the impact of electric fields on both nonretarded and retarded noncovalent interactions between atoms or molecules. To…
Molecular Interactions Induced by a Static Electric Field in Quantum Mechanics and Quantum Electrodynamics
Mohammad Reza Karimpour, Dmitry V. Fedorov, Alexandre Tkatchenko
By means of quantum mechanics and quantum electrodynamics applied to coupled harmonic Drude oscillators, we study the interaction between two neutral atoms or molecules subject to…
Quantum-Mechanical Force Balance Between Multipolar Dispersion and Pauli Repulsion in Atomic van der Waals Dimers
Ornella Vaccarelli, Dmitry V. Fedorov, Martin Stöhr +1
The structure and stability of atomic and molecular systems with van der Waals (vdW) bonding are often determined by the interplay between attractive dispersion interactions and re…
Four-Dimensional Scaling of Dipole Polarizability in Quantum Systems
Peter Szabo, Szabolcs Goger, Jorge Charry +3
Polarizability is a key response property of physical and chemical systems, which has an impact on intermolecular interactions, spectroscopic observables, and vacuum polarization.…
