Ab initio calculation of resonant X-ray scattering in Manganites
Patrizia Benedetti, Jeroen van den Brink, Eva Pavarini +2
We study the origin of the resonant x-ray signal in manganites and generalize the resonant cross-section to the band structure framework. With {\it ab initio} LSDA and LSDA+U calcu…

Jahn-Teller distortion and electronic correlation effects in undoped manganese perovskites
Patrizia Benedetti, Roland Zeyher
The formation of a long-range Jahn-Teller distortion in undoped manganites is studied within the dynamical mean-field theory taking both electron-phonon and electron-electron inter…

Holstein model in infinite dimensions at half-filling
Patrizia Benedetti, Roland Zeyher
The normal state of the Holstein model is studied at half-filling in infinite dimensions and in the adiabatic regime. The dynamical mean-field equations are solved using perturbati…
