Origin of the transitions inversion in rare-earth vanadates
Xue-Jing Zhang, Erik Koch, Eva Pavarini
The surprising inversion of the orbital- and magnetic-order transition temperatures in the RVO3 series with increasing the rare-earth radius makes the series unique among orbitally…

On the mechanism for orbital-ordering in KCuF3
E. Pavarini, E. Koch, A. I. Lichtenstein
The Mott insulating perovskite KCuF3 is considered the archetype of an orbitally-ordered system. By using the LDA+dynamical mean-field theory (DMFT) method, we investigate the mech…

Static vs. dynamical mean field theory of Mott antiferromagnets
G. Sangiovanni, A. Toschi, E. Koch +11
Studying the antiferromagnetic phase of the Hubbard model by dynamical mean field theory, we observe striking differences with static (Hartree-Fock) mean field: The Slater band is…
