XFEL Imaging Techniques for High Energy Density and Inertial Fusion Energy Research at HED-HiBEF
Alejandro Laso Garcia, Mikhail Mishchenko, Victorien Bouffetier +53
The imaging platform developed at the High Energy Density - Helmholtz International Beamline for Extreme Fields (HED-HiBEF) instrument at the European XFEL and its applications to…
Direct simulations of H-He mixtures at planetary interior conditions: demixing, insulator-metal transition and miscibility boundaries
Valentin V. Karasiev, S. X. Hu, Joshua P. Hinz +4
Accurate knowledge of the electrical and thermal conductivities and structural properties of hydrogen-helium mixtures under thermodynamic conditions within and beyond the immiscibi…
Probing the atomic dynamics of ultrafast melting with femtosecond electron diffraction
M. Z. Mo, M. B. Maigler, T. Held +12
Melting is an everyday phase transition that is determined by thermodynamic parameters like temperature and pressure. In contrast, ultrafast melting is governed by the microscopic…
A Momentum-Resolved X-ray Thomson Scattering Benchmark of Electronic-Response Models in Warm Dense Aluminium
Dmitrii S. Bespalov, Ulf Zastrau, Zhandos A. Moldabekov +58
The robust diagnosis of conditions generated in warm dense matter (WDM) experiments remains a persistent challenge. Here we describe the measurement of shock-compressed aluminium a…
Scaling of thin wire cylindrical compression after 100 fs Joule surface heating with material, diameter and laser energy
L. Yang, M. -L. Herbert, C. Bähtz +32
We present the first systematic experimental validation of return-current-driven implosion scaling in micrometer-sized wires irradiated by femtosecond laser pulses. Employing XFEL-…
The Possibility of Hydrogen-Water Demixing in Uranus, Neptune, K2-18b and TOI-270d
Saburo Howard, Ravit Helled, Armin Bergermann +1
The internal structures of Uranus and Neptune remain unknown. In addition, sub-Neptunes are now thought to be the most common type of exoplanets. Understanding the physical process…
Roadmap on Advancements of the FHI-aims Software Package
Joseph W. Abbott, Carlos Mera Acosta, Alaa Akkoush +203
Electronic-structure theory is the foundation of the description of materials including multiscale modeling of their properties and functions. Obviously, without sufficient accurac…
Femtosecond temperature measurements of laser-shocked copper deduced from the intensity of the x-ray thermal diffuse scattering
J. S. Wark, D. J. Peake, T. Stevens +122
We present 50-fs, single-shot measurements of the x-ray thermal diffuse scattering (TDS) from copper foils that have been shocked via nanosecond laser-ablation up to pressures abov…
Model-free Rayleigh weight from x-ray Thomson scattering measurements
Tobias Dornheim, Hannah M. Bellenbaum, Mandy Bethkenhagen +16
X-ray Thomson scattering (XRTS) has emerged as a powerful tool for the diagnostics of matter under extreme conditions. In principle, it gives one access to important system paramet…
First principles simulations of dense hydrogen
Michael Bonitz, Jan Vorberger, Mandy Bethkenhagen +24
Accurate knowledge of the properties of hydrogen at high compression is crucial for astrophysics (e.g. planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) a…
The effect of cloudy atmospheres on the thermal evolution of warm giant planets from an interior modelling perspective
Anna Julia Poser, Ronald Redmer
We are interested in the influence of cloudy atmospheres on the thermal radius evolution of warm exoplanets from an interior modelling perspective. By applying a physically motivat…
Stochastic density functional theory combined with Langevin dynamics for warm dense matter
Rebecca Efrat Hadad, Argha Roy, Eran Rabani +2
This study overviews and extends a recently developed stochastic finite-temperature Kohn-Sham density functional theory to study warm dense matter using Langevin dynamics, specific…
The interaction of intense femtosecond laser pulses with argon microdroplets studied near the soft x-ray emission threshold
R. Irsig, M. Shihab, L. Kazak +4
The extreme ultraviolet plasma emission from liquid microsized argon droplets exposed to intense near-infrared laser pulses has been investigated. Emission from the warm dense matt…
