Probing orbital fluctuations in RVO3 (R = Y, Gd, or Ce) by ellipsometry
J. Reul, A. A. Nugroho, T. T. M. Palstra +1
We study optical excitations across the Mott gap in the multi-orbital Mott-Hubbard insulators RVO3. The multi-peak structure observed in the optical conductivity can be described c…

Hubbard exciton revealed by time-domain optical spectroscopy
Fabio Novelli, Daniele Fausti, Julia Reul +6
We use broadband ultra-fast pump-probe spectroscopy in the visible range to study the lowest excitations across the Mott-Hubbard gap in the orbitally ordered insulator YVO3. Separa…
