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…
Energy Diffusion and Advection Coefficients in Kinetic Simulations of Relativistic Plasma Turbulence
Kai W. Wong, Vladimir Zhdankin, Dmitri A. Uzdensky +2
Turbulent, relativistic nonthermal plasmas are ubiquitous in high-energy astrophysical systems, as inferred from broadband nonthermal emission spectra. The underlying turbulent non…
Dissipation and particle acceleration in astrophysical jets with velocity and magnetic shear: Interaction of Kelvin-Helmholtz and Drift-Kink Instabilities
Tsun Hin Navin Tsung, Gregory R. Werner, Dmitri A. Uzdensky +1
We present 2D particle-in-cell simulations of a magnetized, collisionless, relativistic pair plasma subjected to combined velocity and magnetic-field shear, a scenario typical for…
First-principles measurement of ion and electron energization in collisionless accretion flow
Evgeny A. Gorbunov, Fabio Bacchini, Vladimir Zhdankin +3
We present the largest 3D Particle-in-Cell shearing-box simulations of turbulence driven by the magnetorotational instability, for the first time employing the realistic proton-to-…
Collisionless Magnetorotational Turbulence in Pair Plasmas: Steady-state Dynamics, Particle Acceleration, and Radiative Cooling
Fabio Bacchini, Vladimir Zhdankin, Evgeny A. Gorbunov +4
We present 3D fully kinetic shearing-box simulations of pair-plasma magnetorotational turbulence with unprecedented macro-to-microscopic scale separation. While retrieving the expe…
