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…
Cubic BN optical gap and intragap optically active defects
Anna Tararan, Stefano di Sabatino, Matteo Gatti +6
We report a comprehensive study on the optical properties of cubic boron nitride (c-BN) and its optically active defects. Using electron energy-loss spectroscopy (EELS) within a mo…
Dynamical local connector approximation for electron addition and removal spectra
Marco Vanzini, Lucia Reining, Matteo Gatti
Realistic calculations of electron addition and removal spectra rely most often on Green's functions and complex, non-local self-energies. We introduce a shortcut to obtain the spe…
