Direct measurement of the longitudinal exciton dispersion in hBN by resonant inelastic x-ray scattering

Alessandro Nicolaou, Kari Ruotsalainen, Laura Susana +7

We report resonant inelastic X-ray scattering (RIXS) measurements on the prototypical hexagonal boron nitride hBN layered compound. The RIXS results at the B and N K edges have bee…

Paramagnon dispersion and damping in doped Na $_{x}$ Ca $_{2 - x}$ CuO $_{2}$ Cl $_{2}$

Blair W. Lebert, Benjamin Bacq-Labreuil, Mark P. M. Dean +13

Using Resonant Inelastic X-ray Scattering, we measure the paramagnon dispersion and damping of undoped, antiferromagnetic Ca $_{2}$ CuO $_{2}$ Cl $_{2}$ as well as doped, superconducting Na$_…

Dynamical screening in SrVO $_{3}$ : Inelastic x-ray scattering experiments and ab initio calculations

Kari Ruotsalainen, Alessandro Nicolaou, Christoph J. Sahle +5

We characterize experimentally and theoretically the high-energy dielectric screening properties of the prototypical correlated metal SrVO $_{3}$ . The dynamical structure factor measu…

Resonant inelastic x-ray scattering study of doping and temperature dependence of low-energy excitations in La $_{1 - x}$ Sr $_{x}$ VO $_{3}$

Kari Ruotsalainen, Matteo Gatti, James M. Ablett +5

We present a temperature and doping dependent resonant inelastic X-ray scattering experiment at the V L $_{2, 3}$ and O K edges in La $_{1 - x}$ Sr $_{x}$ VO $_{3}$ for $x = 0$ and $x = 0.1$ . This…

Dispersing and non-dispersing satellites in the photoemission spectra of aluminum

Jianqiang Sky Zhou, Lucia Reining, Alessandro Nicolaou +9

Satellites in electronic spectra are pure many-body effects, and their study has been of increasing interest in both experiment and theory. The presence of satellites due to plasmo…

The isotropic Compton profile difference across the phase transition of VO $_{2}$

Kari O. Ruotsalainen, Juho Inkinen, Tuomas Pylkkänen +4

We studied the isotropic Compton profile of the prototypical oxide VO $_{2}$ across the temperature induced electronic and structural phase transition at T $_{C}$ $\approx$ 340 K. We sho…

Resonant X-ray Emission Spectroscopy With a Standing Wave Excitation

Kari O. Ruotsalainen, Ari-Pekka Honkanen, Stephen P. Collins +6

The Borrmann effect is the anomalous transmission of x rays in perfect crystals under diffraction conditions. It arises from the interference of the incident and diffracted waves,…
