Screening in YBCO at large wave vectors
Simo Huotari, J. Aleksi Soininen, György Vankó +2
We present experimental inelastic x-ray scattering (IXS) and ab initio time-dependent density-functional-theory (TDDFT) studies of YBa2Cu3O7-δ. The response of the low-lying Ba 5p…
Bimagnon studies in cuprates with Resonant Inelastic X-ray Scattering at the O K edge. I - An assessment on La2CuO4 and a comparison with the excitation at Cu L3 and Cu K edges
V. Bisogni, L. Simonelli, L. J. P. Ament +8
We assess the capabilities of magnetic Resonant Inelastic X-ray Scattering (RIXS) at the O edge in undoped cuprates by taking La_{2}CuO_{4} as a benchmark case, based on a seri…
Momentum Distribution and Renormalization Factor in Sodium and the Electron Gas
Simo Huotari, J. Aleksi Soininen, Tuomas Pylkkänen +9
We present experimental and theoretical results on the momentum distribution and the quasiparticle renormalization factor in sodium. From an x-ray Compton-profile measurement of th…
Anisotropic excitonic effects in the energy loss function of hexagonal boron nitride
S. Galambosi, L. Wirtz, J. A. Soininen +7
We demonstrate that the valence energy-loss function of hexagonal boron nitride (hBN) displays a strong anisotropy in shape, excitation energy and dispersion for momentum transfer…
