Reply to Pettersson et al.: Why X-ray spectral features are compatible to continuous distribution models in ambient water Open
“Ambient water properties have been shown to require heterogeneity” (1) is the imperative followed by Pettersson et al. (2) to relate X-ray spectroscopic findings to a heterogeneous or 2-phase model of ambient water. In ref. 3 we question …

Probing hydrogen bond strength in liquid water by resonant inelastic X-ray scattering Open
Local probes of the electronic ground state are essential for understanding hydrogen bonding in aqueous environments. When tuned to the dissociative core-excited state at the O1 s pre-edge of water, resonant inelastic X-ray scattering back…

Compatibility of quantitative X-ray spectroscopy with continuous distribution models of water at ambient conditions Open
Significance Water is the matrix of life and behaves anomalously in many of its properties. Since Wilhelm Conrad Röntgen, two distinct separate phases have been argued to coexist in ambient water, competing with the alternative view of the…

Electronic localization in CaVO3 films via bandwidth control Open
Understanding and controlling the electronic structure of thin layers of quantum materials is a crucial first step towards designing heterostructures where new phases and phenomena, including the metal-insulator transition (MIT), emerge. H…

One-dimensional cuts through multidimensional potential-energy surfaces by tunable x rays Open
The concept of the potential-energy surface (PES) and directional reaction coordinates is the backbone of our description of chemical reaction mechanisms. Although the eigenenergies of the nuclear Hamiltonian uniquely link a PES to its spe…

Dispersive magnetic and electronic excitations in iridate perovskites probed by oxygen -edge resonant inelastic x-ray scattering Open
Resonant inelastic X-ray scattering (RIXS) experiments performed at the\noxygen-$K$ edge on the iridate perovskites {\\SIOS} and {\\SION} reveal a\nsequence of well-defined dispersive modes over the energy range up to $\\sim\n0.8$ eV. The …

Ultrafast dissociation features in RIXS spectra of the water molecule Open
The “pseudo-atomic” peak is formed significantly faster than the atomic-like peak in water RIXS.

Zone plates as imaging analyzers for resonant inelastic x-ray scattering Open
We have implemented and successfully tested an off-axis transmission Fresnel zone plate as a novel type of analyzer optics for resonant inelastic x-ray scattering (RIXS). We achieved a spectral resolution of 64 meV at the nitrogen K-edge (…

A study of the water molecule using frequency control over nuclear dynamics in resonant X-ray scattering Open
We report a full analysis of the resonant inelastic X-ray scattering spectra of H2O, D2O and HDO.

Intralayer doping effects on the high-energy magnetic correlations in NaFeAs Open
We used resonant inelastic x-ray scattering (RIXS) and dynamical susceptibility calculations to study the magnetic excitations in NaFe1$-$xCoxAs ( x=0 , 0.03, and 0.08). Despite a relatively low ordered magnetic moment, collective magnetic…

A Mott insulator continuously connected to iron pnictide superconductors Open
Iron-based superconductivity develops near an antiferromagnetic order and out of a bad metal normal state, which has been interpreted as originating from a proximate Mott transition. Whether an actual Mott insulator can be realized in the …
