Suppressing grid instability and noise in particle-in-cell simulation by smoothing
Gregory R. Werner, Luke C. Adams, John R. Cary
Smoothing short-wavelength charge density variations can stabilize explicit electrostatic particle-in-cell (PIC) plasma simulations against grid heating and cold beam instabilities…
Grid instability growth rates for explicit, electrostatic momentum- and energy-conserving particle-in-cell algorithms
Luke C Adams, Gregory R Werner, John R Cary
When the Debye length is not resolved in a simulation using the most common particle-in-cell (PIC) algorithm, the plasma will unphysically heat until the Debye length becomes resol…
Terahertz Radiation from Laser-Ionized Plasmas
Kathryn A. Wolfinger, Gregory R. Werner, John R. Cary
Numerical simulations of laser-plasma interactions demonstrate the generation of axially polarized electromagnetic pulses (EMPs) that radiate away energy with a characteristic freq…
Accelerated Steady-State Electrostatic Particle-in-Cell Simulation of Langmuir Probes
Gregory R. Werner, Scott Robertson, Thomas G. Jenkins +2
First-principles particle-in-cell (PIC) simulation is a powerful tool for understanding plasma behavior, but this power often comes at great computational expense. Artificially red…
Computing the Paschen curve for argon with speed-limited particle-in-cell simulation
Joseph G. Theis, Gregory R. Werner, Thomas G. Jenkins +1
Upon inclusion of collisions, the speed-limited particle-in-cell (SLPIC) simulation method successfully computed the Paschen curve for argon. The simulations modelled an electron c…
Dispersion and the Speed-Limited Particle-in-Cell Algorithm
Thomas G. Jenkins, Gregory R. Werner, John R. Cary
This paper discusses temporally continuous and discrete forms of the speed-limited particle-in-cell (SLPIC) method first treated by Werner et al. [Phys. Plasmas 25, 123512 (2018)].…
