Delocalization of dark and bright excitons in flat-band materials and the optical properties of VO
Vitaly Gorelov, Lucia Reining, Martin Feneberg +4
The simplest picture of excitons in materials with atomic-like localization of electrons is that of Frenkel excitons, where electrons and holes stay close together, which is associ…
Dynamical screening in SrVO: Inelastic x-ray scattering experiments and ab initio calculations
Kari Ruotsalainen, Alessandro Nicolaou, Christoph J. Sahle +5
We characterize experimentally and theoretically the high-energy dielectric screening properties of the prototypical correlated metal SrVO. The dynamical structure factor measu…
Strategies to build functionals of the density, or functionals of Green's functions: what can we learn?
Ayoub Aouina, Matteo Gatti, Lucia Reining
The many-body problem can in general not be solved exactly, and one of the most prominent approximations is to build perturbation expansions. A huge variety of expansions is possib…
Insights into one-body density matrices using deep learning
Jack Wetherell, Andrea Costamagna, Matteo Gatti +1
The one-body reduced density matrix (1-RDM) of a many-body system at zero temperature gives direct access to many observables, such as the charge density, kinetic energy and occupa…
Re-using model results to determine materials properties: connector theory approach
Marco Vanzini, Ayoub Aouina, Martin Panholzer +2
Computational materials design often profits from the fact that some complicated contributions are not calculated for the real material, but replaced by results of models. We turn…
Dispersing and non-dispersing satellites in the photoemission spectra of aluminum
Jianqiang Sky Zhou, Lucia Reining, Alessandro Nicolaou +9
Satellites in electronic spectra are pure many-body effects, and their study has been of increasing interest in both experiment and theory. The presence of satellites due to plasmo…
