Autor: Magnaterra, M., Sandberg, A., Schilling, H., Warzanowski, P., Pätzold, L., Bergamasco, E., Sahle, Ch. J., Detlefs, B., Ruotsalainen, K., Sala, M. Moretti, Monaco, G., Becker, P., Faure, Q., Thakur, G. S., Songvilay, M., Felser, C., van Loosdrecht, P. H. M., Brink, J. van den, Hermanns, M., Grüninger, M.

The insulating mixed-valent Ir$^{+3.66}$ compound Ba$_4$NbIr$_3$O$_{12}$ hosts two holes per Ir$_3$O$_{12}$ trimer unit. We address the electronic structure via resonant inelastic x-ray scattering (RIXS) at the Ir $L_3$ edge and exact diagonalization

Observation of strong nonlinear interactions in parametric down-conversion of x-rays into ultraviolet radiation

Autor: Sofer, S., Sefi, O., Strizhevsky, E., Collins, S. P., Detlefs, B., Sahle, Ch. J., Shwartz, S.

Nonlinear interactions between x-rays and long wavelengths can be used as a powerful atomic scale probe for light-matter interactions and for properties of valence electrons. This probe can provide novel microscopic information in solids that existin
