Quantification of correlations in quantum many-particle systems
K. Byczuk, J. Kunes, W. Hofstetter +1
We introduce a well-defined and unbiased measure of the strength of correlations in quantum many-particle systems which is based on the relative von Neumann entropy computed from t…

Disproportionation and Metallization at Low-Spin to High-Spin Transition in Multiorbital Mott Systems
Jan Kunes, Vlastimil Krapek
We study the thermally driven spin state transition in a two-orbital Hubbard model with crystal field splitting, which provides a minimal description of the physics of LaCoO3. We e…
