The spin-wave spectrum of the Jahn-Teller system LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We present an analytical calculation of the spin-wave spectrum of the Jahn-Teller system LaTiO3. The calculation includes all superexchange couplings between nearest-neighbor Ti io…

Metallizing the Mott insulator TiOCl by electron doping: a view from LDA+DMFT
L. Craco, M. S. Laad, E. Müller-Hartmann
Based on recent experiments, we describe the Mott insulating, but undimerized state of using the local-density approximation combined with multi-orbital dynamical mean fiel…

The magnetic structure of the Jahn-Teller System LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We investigate the effect of the experimentally observed Jahn-Teller distortion of the oxygen octahedra in LaTiO3 on the magnetic exchange. We present a localized model for the eff…
