First-principles simulation of shocked H-He mixture along the principal Hugoniot
Ammar A. Ellaboudy, Valentin V. Karasiev, S. X. Hu
Recent laser-shock experiments on an H--He mixture containing 11~ helium (atomic fraction) have suggested the presence of an immiscibility region inside Jupiter. Reflectivity m…
Deriving Reliable Nucleation Rates from Metadynamics Simulations: Application to Yukawa Fluids
B. Arnold, J. Daligault, D. Saumon +1
In order to solidify the usefulness of metadynamics in studying nucleation of crystals from supercooled liquids, we provide a specific procedure to calculate nucleation free energy…
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…
Crystal nucleation rates in one-component Yukawa systems
B. Arnold, J. Daligault, D. Saumon +2
Nucleation in the supercooled Yukawa system is relevant for addressing current challenges in understanding a range of crystallizing systems including white dwarf (WD) stars. We use…
X-ray imaging and electron temperature evolution in laser-driven magnetic reconnection experiments at the National Ignition Facility
V. Valenzuela-Villaseca, J. M. Molina, D. B. Schaeffer +13
We present results from X-ray imaging of high-aspect-ratio magnetic reconnection experiments driven at the National Ignition Facility. Two parallel, self-magnetized, elongated lase…
Reproducibility of real-time time-dependent density functional theory calculations of electronic stopping power in warm dense matter
Alina Kononov, Alexander J. White, Katarina A. Nichols +2
Real-time time-dependent density functional theory (TDDFT) is widely considered to be the most accurate available method for calculating electronic stopping powers from first princ…
Toward an accurate equation of state and B1-B2 phase boundary for magnesium oxide to TPa pressures and eV temperatures
Shuai Zhang, Reetam Paul, S. X. Hu +1
By applying auxiliary-field quantum Monte Carlo, we calculate the equation of state (EOS) and B1-B2 phase transition of magnesium oxide (MgO) up to 1 TPa. The results agree with av…
Nature of the bonded-to-atomic transition in liquid silica to TPa pressures
Shuai Zhang, Miguel A. Morales, Raymond Jeanloz +3
First-principles calculations and analysis of the thermodynamic, structural, and electronic properties of liquid SiO characterize the bonded-to-atomic transition at 0.1--1.6 TP…
A novel kinetic mechanism for the onset of fast magnetic reconnection and plasmoid instabilities in collisionless plasmas
W. Fox, G. Fiksel, D. B. Schaeffer +9
Magnetic reconnection can explosively release magnetic energy when opposing magnetic fields merge and annihilate through a current sheet, driving plasma jets and accelerating non-t…
A feasibility study of using X-ray Thomson Scattering to diagnose the in-flight plasma conditions of DT cryogenic implosions
H. Poole, D. Cao, R. Epstein +9
The design of inertial confinement fusion (ICF) ignition targets requires radiation-hydrodynamics simulations with accurate models of the fundamental material properties (i.e., equ…
Elucidation of the subcritical character of the liquid--liquid transition in dense hydrogen
Valentin V. Karasiev, Joshua Hinz, S. X. Hu +1
The liquid-liquid phase transition in high-pressure Hydrogen is a problem of longstanding and controversy. The recent Nature paper by Cheng et al. [vol. 585, p. 217] makes a set of…
Kinetic simulation of magnetic field generation and collisionless shock formation in expanding laboratory plasmas
W. Fox, J. Matteucci, C. Moissard +4
Recent laboratory experiments with laser-produced plasmas have observed and studied a number of fundamental physical processes relevant to magnetized astrophysical plasmas, includi…
Indirect observation of molecular disassociation in solid benzene at low temperatures
F. Yen, S. Z. Huang, S. X. Hu +2
The molecular dynamics of solid benzene are extremely complex; especially below 77 K, its inner mechanics remain mostly unexplored. Benzene is also a prototypical molecular crystal…
