Informing spectral models for dense plasmas with K-edge absorption measurements of warm dense copper
T. Cordova, E. V. Marley, D. A. Chin +14
Warm dense matter remains a challenging regime to characterize experimentally and to model with predictive accuracy. Recent experimental platforms have been developed to generate,…
Physics-Informed Latent Space Dynamics Identification for Time-Dependent NLTE Atomic Kinetics
Jeongwoo Nam, William Anderson, Youngsoo Choi +5
Non-local thermodynamic equilibrium (NLTE) calculations remain a major computational bottleneck in radiation--hydrodynamics, while most existing machine-learning surrogates treat N…
Impact of super-Gaussian electron distributions on plasma K-shell emission
H. P. Le, E. V. Marley, H. A. Scott
Electron distributions in laser-produced plasmas will be driven toward a super-Gaussian distribution due to inverse bremsstrahlung absorption [Langdon, Phys. Rev. Lett. 44, 575 (19…
Physics-Informed Transformation Toward Improving the Machine-Learned NLTE Models of ICF Simulations
Min Sang Cho, Paul E. Grabowski, Kowshik Thopalli +11
The integration of machine learning techniques into Inertial Confinement Fusion (ICF) simulations has emerged as a powerful approach for enhancing computational efficiency. By repl…
Plasma screening in mid-charged ions observed by K-shell line emission
M. Šmıd, O. Humphries, C. Baehtz +24
Dense plasma environment affects the electronic structure of ions via variations of the microscopic electrical fields, also known as plasma screening. This effect can be either est…
Conservative Algorithms for Non-Maxwellian Plasma Kinetics
H. P. Le, J. -L. Cambier
We present a numerical model and a set of conservative algorithms for Non-Maxwellian plasma kinetics with inelastic collisions. These algorithms self-consistently solve for the tim…
Modeling of Inelastic Collisions in a Multifluid Plasma: Excitation and Deexcitation
H. P. Le, J. -L. Cambier
We describe here a model for inelastic collisions for electronic excitation and deexcitation processes in a general, multifluid plasma. The model is derived from kinetic theory, an…
