Nonlocality, entropy creation, and entanglement in quantum many-body systems
Marc Dvorak
We propose a reinterpretation and reformulation of the single-particle Green's function in nonrelativistic quantum many-body theory with an emphasis on normalization. By downfoldin…
Particle conservation in the single-particle Green's function
Marc Dvorak
We argue that the exact single-particle Green's function () in quantum many-body theory does not conserve particle number because the single-particle basis is incomplete. We con…
Atomic and electronic structure of cesium lead triiodide surfaces
Azimatu Seidu, Marc Dvorak, Patrick Rinke +1
The (001) surface of the emerging photovoltaic material cesium lead triiodide (CsPbI3 ) is studied. Using first-principles methods, we investigate the atomic and electronic structu…
A balanced treatment of static and dynamic correlation in free- and Mg-porphyrin
Marc Dvorak, Patrick Rinke
We present an ab-initio dynamical configuration interaction (DCI) study of free- and Mg-porphyrin. DCI is a recently developed active space theory based on the Löwdin downfolding t…
The GW compendium: A practical guide to theoretical photoemission spectroscopy
Dorothea Golze, Marc Dvorak, Patrick Rinke
The GW approximation in electronic structure theory has become a widespread tool for predicting electronic excitations in chemical compounds and materials. In the realm of theoreti…
Observation of Coexistence of Yu-Shiba-Rusinov States and Spin-Flip Excitations
Shawulienu Kezilebieke, Rok Žitko, Marc Dvorak +2
We investigate the spectral evolution in different metal phthalocyanine molecules on NbSe surface using scanning tunnelling microscopy (STM) as a function of the coupling with…
