Understanding cold electron impact on parallel-propagating whistler chorus waves via moment-based quasilinear theory
Opal Issan, Vadim Roytershteyn, Gian Luca Delzanno +1
Earth's magnetosphere hosts a wide range of collisionless particle populations that interact through various wave-particle processes. Among these, cold electrons, with energies bel…
Exascale Implicit Kinetic Plasma Simulations on El~Capitan for Solving the Micro-Macro Coupling in Magnetospheric Physics
Stefano Markidis, Andong Hu, Ivy Peng +9
Our fully kinetic, implicit Particle-in-Cell (PIC) simulations of global magnetospheres on up to 32,768 of El Capitan's AMD Instinct MI300A Accelerated Processing Units (APUs) repr…
Conservative projection-based data-driven model order reduction of a fluid-kinetic spectral solver
Opal Issan, Oleksandr Koshkarov, Federico D. Halpern +2
Kinetic simulations are computationally intensive due to six-dimensional phase space discretization. Many kinetic spectral solvers use the asymmetrically weighted Hermite expansion…
