Reconciling chemical models of X-ray Thomson Scattering with the Bethe -sum rule
Maximilian P. Böhme, Paul Hamann, Veronika A. Kruse +9
X-ray Thomson scattering (XRTS) is a key diagnostic for high-energy-density plasmas, which can exhibit significant quantum effects even at elevated temperatures. XRTS experiments a…
Electronic Signature of Melting Onset in Polycrystalline Copper at Extreme Conditions
Edna R. Toro, Tobias Held, Armin Bergermann +8
Ultrafast melting is fundamentally a structural transition of the ionic lattice, but this rearrangement also reshapes the electronic properties by changing the energy landscape and…
Miscibility and Transport Properties in Hydrogen-Neon Mixtures
Armin Bergermann, Siegfried Glenzer, Arianna Glaeson +1
The mixing behavior of hydrogen with heavier elements plays a key role in modeling the interiors of giant planets such as Jupiter and Saturn. Using density functional theory combin…
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…
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…
