Turbulence and particle acceleration in a relativistic plasma
Cristian Vega, Stanislav Boldyrev, Vadim Roytershteyn +1
In a collisionless plasma, the energy distribution function of plasma particles can be strongly affected by turbulence. In particular, it can develop a non-thermal power-law tail a…
Energy-conserving explicit and implicit time integration methods for the multi-dimensional Hermite-DG discretization of the Vlasov-Maxwell equations
Cecilia Pagliantini, Gianmarco Manzini, Oleksandr Koshkarov +2
We study the conservation properties of the Hermite-discontinuous Galerkin (Hermite-DG) approximation of the Vlasov-Maxwell equations. In this semi-discrete formulation, the total…
Nonlinear coupling of whistler waves to oblique electrostatic turbulence enabled by cold plasma
Vadim Roytershteyn, Gian Luca Delzanno
Kinetic simulations and theory demonstrate that whistler waves can excite oblique, short-wavelength fluctuations through secondary drift instabilities if a population of sufficient…
Dissipation measures in weakly-collisional plasmas
O. Pezzi, H. Liang, J. L. Juno +8
The physical foundations of the dissipation of energy and the associated heating in weakly collisional plasmas are poorly understood. Here, we compare and contrast several measures…
