Spin-orbital excitation continuum and anomalous electron-phonon interaction in the Mott insulator LaTiO
C. Ulrich, G. Khaliullin, M. Guennou +3
Raman scattering experiments on stoichiometric, Mott-insulating LaTiO over a wide range of excitation energies reveal a broad electronic continuum which is featureless in the p…

Orbital excitations in titanates
C. Ulrich, A. Gössling, M. Grüninger +6
Raman scattering is used to observe pronounced electronic excitations around 230 meV - well above the two-phonon range - in the Mott insulators LaTiO and YTiO. Based on the…
