Cu $K$-edge Resonant Inelastic X-Ray Scattering in Edge-Sharing Cuprates (2007)
Vernay, F., Moritz, B., Elfimov, I., Geck, J., Hawthorn, D., Devereaux, T. P., ...
We present calculations for resonant inelastic x-ray scattering (RIXS) in edge-shared copper oxide systems, such as CuGeO$_{3}$ and Li$_{2}$CuO$_{2}$, appropriate for hard x-ray scattering where the...
Interface hole-doping in cuprate-titanate superlattices (2006)
Pavlenko, N., Elfimov, I., Kopp, T., Sawatzky, G. A.
The electronic structure of interfaces between YBa$_2$Cu$_3$O$_6$ and SrTiO$_3$ is studied using local spin density approximation (LSDA) with intra-atomic Coulomb repulsion (LSDA+U). We find a...
Zooming-in on the charge ordering in YBa2Cu3O6.5 (2004)
Feng, D. L., Rusydi, A., Abbamonte, P., Venema, L., Elfimov, I., Liang, R., ...
We report direct evidence of charge/orbital ordering of low energy electronic states of $Cu$ in YBa$_2$Cu$_3$O$_{6+x}$ ortho-II phase in both the $CuO_3$ chain and the CuO$_2$ plane. Huge enhancement...
