Volume Collapse Without a Structural Transition in Shock-Compressed FeO

C. Crépisson, T. Stevens, M. Fitzgerald +121

We report x-ray diffraction and emission spectroscopy of FeO under laser-driven shock compression between 31-199 GPa. FeO retains the B1 (rocksalt) structure along the Hugoniot to…

Enhancing the Efficiency of Time-Dependent Density Functional Theory Calculations of Dynamic Response Properties

Zhandos A. Moldabekov, Sebastian Schwalbe, Uwe Hernandez Acosta +4

X-ray Thomson scattering (XRTS) constitutes an essential technique for diagnosing material properties under extreme conditions, such as high pressures and intense laser heating. Ti…

Orientational Effects in the Low Pair Continuum of Aluminium

Thomas Gawne, Zhandos A Moldabekov, Oliver S Humphries +6

We compare the predictions of the dynamic structure factor (DSF) of ambient polycrystalline aluminium from time-dependent density functional theory (TDDFT) in the pair continuum re…

Strong geometry dependence of the X-ray Thomson Scattering Spectrum in single crystal silicon

Thomas Gawne, Zhandos A. Moldabekov, Oliver S. Humphries +17

We report on results from an experiment at the European XFEL where we measured the x-ray Thomson scattering (XRTS) spectrum of single crystal silicon with ultrahigh resolution. Com…

Shock-driven amorphization and melt in FeO

Céline Crépisson, Alexis Amouretti, Marion Harmand +28

We present measurements on FeO amorphization and melt under laser-driven shock compression up to 209(10) GPa via time-resolved in situ x-ray diffraction. At 122(3) GPa, a d…

Phase transitions of FeO under laser shock compression

A. Amouretti, C. Crépisson, S. Azadi +22

We present in-situ x-ray diffraction and velocity measurements of FeO under laser shock compression at pressures between 38-116 GPa. None of the phases reported by static c…

Resonant inelastic x-ray scattering in warm-dense Fe compounds beyond the SASE FEL resolution limit

Alessandro Forte, Thomas Gawne, Karim K. Alaa El-Din +19

Resonant inelastic x-ray scattering (RIXS) is a widely used spectroscopic technique, providing access to the electronic structure and dynamics of atoms, molecules, and solids. Howe…
