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…
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-in-cell simulations of expanding high energy density plasmas with laser ray tracing
K. V. Lezhnin, S. R. Totorica, A. S. Hyder +5
The design and analysis of high energy density (HED) laser experiments typically rely on radiation hydrodynamics simulations. However, some laser-plasma interaction regimes are not…
Nonthermal electron and ion acceleration by magnetic reconnection in large laser-driven plasmas
Samuel Totorica, Masahiro Hoshino, Tom Abel +1
Magnetic reconnection is a fundamental plasma process that is thought to play a key role in the production of nonthermal particles associated with explosive phenomena in space phys…
Simplex-in-Cell Technique for Collisionless Plasma Simulations
Julian Kates-Harbeck, Samuel Totorica, Jonathan Zrake +1
We extend the simplex-in-cell (SIC) technique recently introduced in the context of collisionless dark matter fluids (Abel et al. 2012; Hahn et al. 2012) to the case of collisionle…
