Laboratory measurements of energy partitioning and anomalous electron heating in magnetized, perpendicular collisionless shocks
V. Valenzuela-Villaseca, S. Totorica, J. Griff-McMahon +6
We present laboratory results on energy partitioning from supercritical, magnetized collisionless shock experiments (, ). We report the first ob…
Expansion-Driven Self-Magnetization of High-Energy-Density Plasmas
K. V. Lezhnin, S. R. Totorica, J. Griff-McMahon +4
Understanding plasma self-magnetization is one of the fundamental challenges in both laboratory and astrophysical plasmas. Self-magnetization can modify the plasma transport proper…
Particle collisionality in scaled kinetic plasma simulations
S. R. Totorica, K. V. Lezhnin, W. Fox
Kinetic plasma processes, such as magnetic reconnection, collisionless shocks, and turbulence, are fundamental to the dynamics of astrophysical and laboratory plasmas. Simulating t…
Symmetries and conservation laws in discrete spacetime
Samuel Richard Totorica
Noether's theorem connects symmetries to invariants in continuous systems, however its extension to discrete systems has remained elusive. Recognizing the lowest-order finite diffe…
