Dynamical Mean Field Theory for Perovskites

P. Lombardo, J. Schmalian, M. Avignon +1

Using the Hubbard Hamiltonian for transition metal-3d and oxygen-2p states with perovskite geometry, we present a dynamical mean field theory which becomes exactin the limit of lar…

A new approach for perovskites in large dimensions

J. Schmalian, P. Lombardo, M. Avignon +1

Using the Hubbard Hamiltonian for transition metal-3d and oxygen-2p states with perovskite geometry, we propose a new scaling procedure for a nontrivial extension of these systems…
