X-ray techniques have been used for more than a century to study the atomic and electronic
structure in practically any type of material. The advent of correlated electron systems, in …

In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress
as a spectroscopic technique. This is a direct result of the availability of high-brilliance …

The creation of a 1s core hole in a 3d transition metal ion gives rise to an emission spectrum
that can be recorded using a crystal analyzer. K shell X-ray spectroscopy using an analyser …

Knowledge of the dynamics of many-electron systems is of fundamental importance to all
disciplines of condensed matter physics. A very effective access to electron dynamics is …

The generation of radiation with well-defined frequency and wavelength, and the ability to
precisely determine these quantities, are of fundamental importance in physics and other …

We show that in resonant inelastic x-ray scattering (RIXS) at the copper L and M edge direct
spin-flip scattering is in principle allowed. We demonstrate how this possibility can be …

We use resonant inelastic x-ray scattering (RIXS) at the OK-and Cu K-edges to investigate
the doping dependence and temperature dependence of low-energy plasmon excitations in …

We report an Ir L 3 edge resonant inelastic x-ray scattering measurement of the low-lying
electronic excitations in Sr 2 IrO 4 over the complete Brillouin zone of the IrO 2 plane. A …

We report a resonant inelastic x-ray scattering (RIXS) study of charge excitations in the
electron-doped high-T c superconductor Nd 1.85 Ce 0.15 CuO 4. The intraband and …

We present scanning tunneling microscopy and spectroscopy experiments on the novel J
eff= 1/2 Mott insulator Sr 2 Ir O 4. Local density of states (LDOS) measurements show an …
