Natural Extension of Hartree-Fock through extremal -fermion information: Overview and application to the lithium atom
Carlos L. Benavides-Riveros, Christian Schilling
Fermionic natural occupation numbers do not only obey Pauli's exclusion principle but are even stronger restricted by so-called generalized Pauli constraints. Whenever given natura…
Towards a formal definition of static and dynamic electronic correlations
Carlos L. Benavides-Riveros, Nektarios N. Lathiotakis, Miguel A. L. Marques
Some of the most spectacular failures of density-functional and Hartree-Fock theories are related to an incorrect description of the so-called static electron correlation. Motivate…
Relating correlation measures: the importance of the energy gap
Carlos L. Benavides-Riveros, Nektarios N. Lathiotakis, Christian Schilling +1
The concept of correlation is central to all approaches that attempt the description of many-body effects in electronic systems. Multipartite correlation is a quantum information t…
Reconstructing quantum states from single-party information
Christian Schilling, Carlos L. Benavides-Riveros, Péter Vrana
The possible compatibility of density matrices for single-party subsystems is described by linear constraints on their respective spectra. Whenever some of those quantum marginal c…
