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…
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…
Spontaneous magnetization of collisionless plasma through the action of a shear flow
Muni Zhou, Vladimir Zhdankin, Matthew W. Kunz +2
We study in a fully kinetic framework the generation of seed magnetic fields through the Weibel instability driven in an initially unmagnetized plasma by a large-scale shear force.…
Influence of a large-scale field on energy dissipation in magnetohydrodynamic turbulence
Vladimir Zhdankin, Stanislav Boldyrev, Joanne Mason
In magnetohydrodynamic (MHD) turbulence, the large-scale magnetic field sets a preferred local direction for the small-scale dynamics, altering the statistics of turbulence from th…
Kinetic turbulence in relativistic plasma: from thermal bath to non-thermal continuum
Vladimir Zhdankin, Gregory R. Werner, Dmitri A. Uzdensky +1
We present results from particle-in-cell simulations of driven turbulence in magnetized, collisionless, and relativistic pair plasma. We find that fluctuations are consistent with…
Scalings of intermittent structures in magnetohydrodynamic turbulence
Vladimir Zhdankin, Stanislav Boldyrev, Dmitri A. Uzdensky
Turbulence is ubiquitous in plasmas, leading to rich dynamics characterized by irregularity, irreversibility, energy fluctuations across many scales, and energy transfer across man…
Intermittency of Energy Dissipation in Alfvenic Turbulence
Vladimir Zhdankin, Stanislav Boldyrev, Christopher H. K. Chen
We investigate the intermittency of energy dissipation in Alfvenic turbulence by considering the statistics of the coarse-grained energy dissipation rate, using direct measurements…
Energy dynamics and current sheet structure in fluid and kinetic simulations of decaying magnetohydrodynamic turbulence
K. D. Makwana, V. Zhdankin, H. Li +2
Simulations of decaying magnetohydrodynamic (MHD) turbulence are performed with a fluid and a kinetic code. The initial condition is an ensemble of long-wavelength, counter-propaga…
