Spin crossover in FeO under shock compression
Lélia Libon, Alessandra Ravasio, Silvia Pandolfi +17
FeO (wüstite), which exhibits complex electronic and structural properties with increasing pressure and temperature, is a key mineralogical phase for understanding deep planetary i…
Comment on "Comments regarding "Transonic dislocation propagation in diamond" by Katagiri, et al. (Science 382, 69-72, 2023)" by Hawreliak, et al. (arXiv:2401.04213)
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
In their comment (1), Hawreliak et al. claims that our observation of stacking fault formation and transonic dislocation propagation in diamond (2) is not valid as they interpret t…
Laser-driven shock compression and equation of state of FeO up to 700 GPa
Alexis Amouretti, Marion Harmand, Bruno Albertazzi +7
We report here the first equation of state measurements of FeO obtained with laser-driven shock compression. The data are in excellent agreement with previous dynamic and s…
Transonic Dislocation Propagation in Diamond
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
The motion of line defects (dislocations) has been studied for over 60 years but the maximum speed at which they can move is unresolved. Recent models and atomistic simulations pre…
A Task Programming Implementation for the Particle in Cell Code Smilei
Francesco Massimo, Mathieu Lobet, Julien Derouillat +5
An implementation of the electromagnetic Particle in Cell loop in the code Smilei using task programming is presented. Through OpenMP, the macro-particles operations are formulated…
Characterization of the stability and dynamics of a laser-produced plasma expanding across strong magnetic field
Weipeng Yao, Julien Capitaine, Benjamin Khiar +5
Magnetized laser-produced plasmas are central to many new studies in laboratory astrophysics, inertial confinement fusion, and industrial applications. Here we present the results…
Numerical study of Langmuir wave coalescence in laser-plasma interaction
F. Pérez, F. Amiranoff, C. Briand +7
Type-III-burst radio signals can be mimicked in the laboratory via laser-plasma interaction. Instead of an electron beam generating Langmuir waves (LW) in the interplanetary medium…
Metallization of Shock-Compressed Liquid Ammonia
A. Ravasio, M. Bethkenhagen, J. -A. Hernandez +8
Ammonia is predicted to be one of the major components in the depths of the ice giant planets Uranus and Neptune. Their dynamics, evolution, and interior structure are insufficient…
Laboratory disruption of scaled astrophysical outflows by a misaligned magnetic field
G. Revet, B. Khiar, E. Filippov +20
The shaping of astrophysical outflows into bright, dense and collimated jets due to magnetic pressure is here investigated using laboratory experiments. We notably look at the impa…
Adaptive SIMD optimizations in particle-in-cell codes with fine-grain particle sorting
Arnaud Beck, Julien Dérouillat, Mathieu Lobet +6
Particle-In-Cell (PIC) codes are broadly applied to the kinetic simulation of plasmas, from laser-matter interaction to astrophysics. Their heavy simulation cost can be mitigated b…
Characterising equation of state and optical properties of dynamically pre-compressed materials
M. Guarguaglini, J. -A. Hernandez, A. Benuzzi-Mounaix +4
Characterising materials at pressures of several megabar and temperatures of a few thousand Kelvin is critical for the understanding of the Warm Dense Matter regime and to improve…
Equation of state and optical properties of shock-compressed C:H:N:O molecular mixtures
M. Guarguaglini, J. -A. Hernandez, T. Okuchi +14
Water, ethanol, and ammonia are the key components of the mantles of Uranus and Neptune. To improve structure and evolution models and give an explanation of the magnetic fields an…
From quantum to classical modelling of radiation reaction: a focus on the radiation spectrum
F. Niel, C. Riconda, F. Amiranoff +5
Soon available multi petawatt ultra-high-intensity (UHI) lasers will allow us to probe high-amplitude electromagnetic fields interacting with either ultra-relativistic electron bea…

We report an experimental study of the phase diagrams of periclase (MgO), enstatite (MgSiO3) and forsterite (Mg2SiO4) at high pressures. We investigated with laser driven decaying…
Melting of iron close to Earth's inner core boundary conditions and beyond
M. Harmand, A. Ravasio, S. Mazevet +23
Several important geophysical features such as heat flux at the Core-Mantle Boundary or geodynamo production are intimately related with the temperature profile in the Earth's core…
Are LGRBs biased tracers of star formation? Clues from the host galaxies of the Swift/BAT6 complete sample of LGRBs. I: Stellar mass at z<1
S. D. Vergani, R. Salvaterra, J. Japelj +20
LGRBs are associated with massive stars and are therefore linked to star formation. The conditions necessary to produce LGRBs can affect the relation between the LGRB rate and star…
