Localization of strongly correlated electrons as Jahn-Teller polarons in manganites
Y. -F. Yang, K. Held
A realistic modeling of manganites should include the Coulomb repulsion between electrons, the Hund's rule coupling to spins, and Jahn-Teller phonons. Solving such a…
Dynamical vertex approximation - a step beyond dynamical mean field theory
A. Toschi, A. A. Katanin, K. Held
We develop a diagrammatic approach with local and nonlocal self-energy diagrams, constructed from the local irreducible vertex. This approach includes the local correlations of dyn…
Pressure-induced metal-insulator transition in LaMnO3 is not of Mott-Hubbard type
A. Yamasaki, M. Feldbacher, Y. -F. Yang +2
Calculations employing the local density approximation combined with static and dynamical mean-field theories (LDA+U and LDA+DMFT) indicate that the metal-insulator transition obse…
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…
