Mapping of Electron-Hole Excitations in the Charge-Density-Wave System 1T-TiSe2 Using Resonant Inelastic X-Ray Scattering

Thorsten Schmitt, Helmuth Berger, Philipp Aebi

In high-resolution resonant inelastic x-ray scattering at the Ti L edge of the charge-density-wave system 1T-TiSe2, we observe sharp low energy loss peaks from electron-hole pair excitations developing at low temperature. These excitations are strongly dis ...

Pair correlations, short-range order, and dispersive excitations in the quasi-kagome quantum magnet volborthite

Henrik Moodysson Rønnow, Goran Nilsen

We present spatial and dynamic information on the s = 1/2 distorted kagome antiferromagnet volborthite, Cu3V2O7(OD)(2) center dot 2D(2)O, obtained by polarized and inelastic neutron scattering. The instantaneous structure factor, S(Q), is dominated by near ...

Time-Resolved Optical and X-Ray Spectroscopy of Rhenium Based Molecular Complexes

Amal El Nahhas

The photocycle of rhenium carbonyl complexes, type facial-[Re(L)(CO)3(diimine)]n [L=halide / n=0, L=4-Ethyl-pyridine (Etpy)- Imidazole (ImH) /n=+1, diimine= bpy , 10- phenanthroline (phen), 4,4'-dimethyl-2,2'-bpy (dmb)] was studied using a set of ultrafast ...

Evidence for core-hole-mediated inelastic x-ray scattering from metallic Fe1.087Te

Henrik Moodysson Rønnow, Marco Grioni, Thorsten Schmitt, Marco Guarise, Ping-Hui Lin, Dirk Van der Marel

We present a detailed analysis of resonant inelastic x-ray scattering from Fe1.087Te with unprecedented energy resolution. In contrast to the sharp peaks typically seen in insulating systems at the transition-metal L-3 edge, we observe spectra which show d ...

Crystal field and low energy excitations measured by high resolution RIXS at the L-3 edge of Cu, Ni and Mn

Marco Grioni, Thorsten Schmitt, Helmuth Berger, Xiao Wang

Resonant inelastic x-ray scattering in the soft x-ray regime has been profiting much from technical advances that have lowered considerably the instrumental linewidth. At the ADRESS beam line of the Swiss Light Source the SAXES spectrometer can be used to ...

Kinks in the angle resolved photoemission and inelastic x-ray spectra of high temperature superconductors

Jeff Graf

Though the high superconducting transition temperature (Tc) is the most interesting technological aspect of high temperature superconductors, the complex way in which the spin, lattice and electronic degrees of freedom interplay, makes them of the highest ...

Comparison of bulk-sensitive spectroscopic probes of Yb valence in Kondo systems

Marco Grioni, Luca Moreschini

We exploited complementary synchrotron radiation spectroscopies to study the Yb 4f electronic configuration in three representative intermediate-valence materials: YbAl3, YbInCu4, and YbCu2Si2. High-resolution x-ray absorption (PFY-XAS), resonant inelastic ...

SAXES, a high resolution spectrometer for resonant x-ray emission in the 400-1600 eV energy range

Marco Grioni, Thorsten Schmitt, Xiao Wang

We present a 5 m long spectrometer for soft x rays to be used at a synchrotron radiation beamline for resonant x-ray emission spectroscopy and resonant inelastic x-ray scattering in the 400-1600 eV energy range. It is based on a variable line spacing spher ...

X-ray absorption, refraction and resonant scattering tensors in selenated protein crystals: implications for data collection strategies in macromolecular crystallography

Philip Pattison

Polarized fluorescence spectra were recorded in the vicinity of the Se and Br K edges on crystals of the selenated protein aldose reductase in complex with a brominated inhibitor molecule. The X-ray absorption, refraction and resonant scattering tensors as ...

Localized electronic excitations in NiO studied with resonant inelastic X-ray scattering at the Ni M threshold: Evidence of spin flip

Marco Grioni, Xiao Wang

We studied the neutral electronic excitations of NiO localized at the Ni sites by measuring the resonant inelastic x-ray scattering (RIXS) spectra at the Ni M-2,M-3 edges. The good energy resolution allows an unambiguous identification of several spectral ...
