- Abstract
- The description of transition metal oxides like LaMnO3 requires the use of models which take into account the orbital structure. The simplest such model is the two-orbital Hubbard model, which we study within dynamical mean-field theory, using Wilson's numerical renormalization group (NRG) to solve the quantum impurity problem arising in this approach. We present results for the Mott-Hubbard transition and antiferromagnetic phase close to half filling. (c) 2006 Elsevier B.V. All rights reserved.
