TL;DR: In this paper, the authors show direct observation of an abrupt insulator-to-metal transition in dense liquid deuterium, which may constrain the region of hydrogen-helium immiscibility and the boundary layer pressure in standard models of the internal structure of gas-giant planets.

TL;DR: In this article, basic thermodynamic and transport properties of hydrogen-helium-water mixtures for the extreme conditions along Jupiter's adiabat via ab initio simulations are determined in an accurate and consistent data set.

TL;DR: In this paper, an improved ab initio hydrogen EOS, H-REOS, is presented, and the internal structure and thermal evolution of Jupiter within the standard three-layer approach.

TL;DR: In this article, an improved ab initio hydrogen equation of state, H-REOS.2, was proposed to compute the internal structure and thermal evolution of Jupiter within the standard three-layer approach, which is consistent with the observed 2 or more times solar heavy element abundances in Jupiter's atmosphere.

TL;DR: The dynamics of ultrafast heating in cryogenic hydrogen initiated by a ≲300 fs, 92 eV free electron laser x-ray burst agrees with radiation hydrodynamics simulations based on a conductivity model for partially ionized plasma that is validated by two-temperature density-functional theory.
