A Linear Instability and Damping in the Acoustic Dispersion Relation of Fluids Subject to Inverse Compton Drag
Yiting Wang, Sebastian Heinz, Vladimir Zhdankin
Radiation drag from inverse-Compton scattering of an external radiation field changes the acoustic dispersion relation of a relativistic fluid. We derive the linear dispersion rela…
Nonlinear Landau Collisions Without Collision Tensors
R. Jorge, B. Herfray, C. Vega +1
Far-from-equilibrium plasmas require nonlinear Coulomb collisions, but direct three-dimensional Hermite discretization of the Landau operator needs an impractical dense tensor. By…
Nonthermal Particle Acceleration by Magnetic Pumping in Pulsating Plasmas
Giuseppe Arrò, Vladimir Zhdankin, Fabio Bacchini
We present a new "pulsating box" setup to investigate particle acceleration in high-beta plasmas undergoing compression-expansion cycles. Our fully kinetic simulations show that pa…
Fast Magnetosonic Turbulence in Two-Dimensional Relativistic Plasmas
Petr Ugarov, Vladimir Zhdankin, Giuseppe Arrò
We present fully kinetic simulations of driven 2D turbulence in a relativistic plasma, designed for the first time to induce a fast magnetosonic cascade. As the driving strength in…
Radiative relativistic turbulence as an in situ pair-plasma source in blazar jets
John Mehlhaff, Muni Zhou, Vladimir Zhdankin
As powerful gamma-ray engines, blazars -- relativistic plasma jets launched toward Earth from active galactic nuclei -- are manifestly high-energy particle accelerators. Yet, exact…
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…
