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…
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…
Numerical Investigation of Non-equilibrium Electron Effects on the Collisional Ionization Rate in the Collisional-Radiative Model
M. S. Cho, H. -K. Chung, M. E. Foord +2
The interplay of kinetic electron physics and atomic processes in ultrashort laser-plasma interactions provides a comprehensive understanding of electron energy distribution's impa…
