Real Space Green's Function Approach to RIXS
J. J. Kas, J. J. Rehr, J. A. Soininen +1
We present an ab initio theory of core- and valence resonant inelastic x-ray scattering (RIXS) based on a real-space multiple scattering Green's function formalism and a quasi-boso…
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…
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…
Exciton spectroscopy of hexagonal boron nitride using non-resonant x-ray Raman scattering
Yejun Feng, J. A. Soininen, A. L. Ankudinov +5
We report non-resonant x-ray Raman scattering (XRS) measurements from hexagonal boron nitride for transferred momentum from 2 to 9 along directions both in and out…
Many-pole model of inelastic losses in x-ray absorption spectra
J. J. Kas, A. P. Sorini, M. P. Prange +3
Inelastic losses are crucial to a quantitative analysis of x-ray absorption spectra. However, current treatments are semi-phenomenological in nature. Here a first-principles, many-…
X-ray Raman scattering study of aligned polyfluorene
S. Galambosi, M. Knaapila, J. A. Soininen +6
We present a non-resonant inelastic x-ray scattering study at the carbon K-edge on aligned poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] and show that the x-ray Raman scattering te…
