Can the electron density be interpreted information-theoretically? A critical analysis using quantum information theory
Guillaume Acke, Daria Van Hende, Ruben Van der Stichelen +1
Many quantum chemical similarity measures have been derived and substantiated by applying concepts and quantities from information theory to the electron density. To justify the us…
Spin-constrained Hartree-Fock and the generator coordinate method for the 2-site Hubbard model
Stijn De Baerdemacker, Amir Ayati, Hugh G. A. Burton +3
We present a mathematical analysis of the spin-constrained Hartree-Fock solutions (CHF) of the 2-site Hubbard model. The analysis sheds light on the spin symmetry breaking process…
Maximum Probability Domains for Hubbard Models
Guillaume Acke, Stijn De Baerdemacker, Pieter W. Claeys +4
The theory of Maximum Probability Domains (MPDs) is formulated for the Hubbard model in terms of projection operators and generating functions for both exact eigenstates as well as…
