Accelerating the Particle-In-Cell code ECsim with OpenACC
Elisabetta Boella, Nitin Shukla, Filippo Spiga +3
The Particle-In-Cell (PIC) method is a computational technique widely used in plasma physics to model plasmas at the kinetic level. In this work, we present our effort to prepare t…
Velocity-Space Signatures of Energy Transfer for Ion-Acoustic Instabilities
Mahmoud Saad Afify, Kristopher G. Klein, Mihailo M. MartinoviÄ +1
Context. Observations by Parker Solar Probe (PSP) of electrostatic waves suggest that electrostatic instabilities, including the ion-ion-acoustic instability (IIAI) frequently obse…
Energetic spectra from semi-implicit particle-in-cell simulations of magnetic reconnection
K. M. Schoeffler, F. Bacchini, K. Kormann +2
Astrophysical observations suggest that magnetic reconnection in relativistic plasmas plays an important role in the acceleration of energetic particles. Modeling this accurately r…
Optimal Landau-type closure parameters for two-fluid simulations of plasma turbulence at kinetic scales
Simon Lautenbach, Jeremiah Lübke, Maria Elena Innocenti +2
Two fluid simulations using local Landau-fluid closures derived from linear theory provide an efficient computational framework for plasma modelling, since they bridge the gap betw…
Particle-in-cell simulations of the tearing instability for relativistic pair plasmas
K. M. Schoeffler, B. Eichmann, F. Pucci +1
Two-dimensional particle-in-cell (PIC) simulations explore the collisionless tearing instability developing in a Harris equilibrium configuration in a pair (electron-positron) plas…
Electrostatic Bursts Generated by the Ion-Ion Acoustic Instability with Solar Wind Plasma Parameters
Mahmoud Saad Afify, Jürgen Dreher, Kevin Schoeffler +2
This study is motivated by recent observations from the Parker Solar Probe (PSP) mission, which have been identified as the ion-acoustic waves from 15 to 25 solar radii. These obse…
