Deep energy-pressure regression for a thermodynamically consistent EOS model
Autor: Dayou Yu, Deep Shankar Pandey, Joshua Hinz, Deyan Mihaylov, Valentin V Karasiev, S X Hu, Qi Yu
Publikováno v: Machine Learning: Science and Technology, Vol 5, Iss 1, p 015031 (2024)
In this paper, we aim to explore novel machine learning (ML) techniques to facilitate and accelerate the construction of universal equation-Of-State (EOS) models with a high accuracy while ensuring important thermodynamic consistency. When applying M

Enhanced asymmetry in few-cycle attosecond pulse ionization of He in the vicinity of autoionizing resonances
Autor: J M Ngoko Djiokap, S X Hu, Wei-Chao Jiang, Liang-You Peng, Anthony F Starace
Publikováno v: New Journal of Physics, Vol 14, Iss 9, p 095010 (2012)
By solving the two-active-electron, time-dependent Schrödinger equation in its full dimensionality, we investigate the carrier-envelope phase (CEP) dependence of single ionization of He to the He ^+ (1s) state triggered by an intense few-cycle attos

Probing atomic physics at ultrahigh pressure using laser-driven implosions
Autor: S. X. Hu, David T. Bishel, David A. Chin, Philip M. Nilson, Valentin V. Karasiev, Igor E. Golovkin, Ming Gu, Stephanie B. Hansen, Deyan I. Mihaylov, Nathaniel R. Shaffer, Shuai Zhang, Timothy Walton
Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-11 (2022)
Atoms and molecules under extreme temperature and pressure can be investigated using dense plasmas achieved by laser-driven implosion. Here the authors report spectral change of copper in billions atmosphere pressure that can only be explained by a s

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-12 (2022)
Charged particle interaction and energy dissipation in plasma is fundamentally interesting. Here the authors study proton stopping in laser-produced plasma for the moderate to strong coupling with electrons.

Interspecies radiative transition in warm and superdense plasma mixtures
Autor: S. X. Hu, V. V. Karasiev, V. Recoules, P. M. Nilson, N. Brouwer, M. Torrent
Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-8 (2020)
Matter at extremely high density and pressure behaves differently than at ambient conditions. Here the authors use first-principles calculations to show the existence of interspecies radiative and dipole-forbidden transitions in warm and superdense p

Thermal transport in warm dense matter revealed by refraction-enhanced x-ray radiography with a deep-neural-network analysis
Autor: S. Jiang, O. L. Landen, H. D. Whitley, S. Hamel, R. London, D. S. Clark, P. Sterne, S. B. Hansen, S. X. Hu, G. W. Collins, Y. Ping
Publikováno v: Communications Physics. 6
Transport properties of high energy density matter affect the evolution of many systems, ranging from the geodynamo in the Earth’s core, to hydrodynamic instability growth in inertial confinement fusion capsules. Large uncertainties of these proper
