Nonlinear kinetic closures for linear instabilities
Elizabeth J. Paul, Archis Joglekar, Alexey Knyazev
Landau fluid closures are linear in the evolved moments. We examine the consequences of relaxing linearity. As an example, we introduce the nonlinear exact kinetic response closure…
On the evolution of a large-amplitude, weakly-collisional electron plasma wave
A. S. Joglekar, A. G. R. Thomas
Vlasov-Poisson-Fokker-Planck (VPFP) simulations of large-amplitude electron plasma waves, where the bounce frequency is much larger than the collision frequency, $ω_B \gg ν_\text{e…
Machine learning of hidden variables in multiscale fluid simulation
Archis S. Joglekar, Alexander G. R. Thomas
Solving fluid dynamics equations often requires the use of closure relations that account for missing microphysics. For example, when solving equations related to fluid dynamics fo…
Control Systems and Data Management for High-Power Laser Facilities
Scott Feister, Kevin Cassou, Stephen Dann +9
The next generation of high-power lasers enables repetition of experiments at orders of magnitude higher frequency than was possible using the prior generation. Facilities requirin…
Unsupervised Discovery of Inertial-Fusion Plasma Physics using Differentiable Kinetic Simulations and a Maximum Entropy Loss Function
Archis S. Joglekar, Alexander G. R. Thomas
Plasma supports collective modes and particle-wave interactions that leads to complex behavior in inertial fusion energy applications. While plasma can sometimes be modeled as a ch…
Observations of Pressure Anisotropy Effects within Semi-Collisional Magnetized-Plasma Bubbles
E. R. Tubman, A. S. Joglekar, A. F. A. Bott +21
Magnetized plasma interactions are ubiquitous in astrophysical and laboratory plasmas. Various physical effects have been shown to be important within colliding plasma flows influe…
