Mott-Hubbard exciton in the optical conductivity of YTiO 3 and SmTiO 3
In the Mott-Hubbard insulators YTiO3 and SmTiO3 we study optical excitations from the lower to the upper Hubbard band, ∣∣d1d1⟩→∣∣d0d2⟩. The multipeak structure observed in the optical conductivity reflects the multiplet structure of the upper Hubbard band in a multiorbital system. Absorption bands a...
