3D Kinetic Simulations of Driven Reconnection in Merging Flux Tubes
Camille Granier, Fabio Bacchini, Daniel Groselj +1
We present 2D and 3D Particle-in-Cell simulations of driven collisionless magnetic reconnection triggered by the compression and merger of two Lundquist-type force-free flux tubes…

Particle-in-Cell Methods for Simulations of Sheared, Expanding, or Escaping Astrophysical Plasma
Fabio Bacchini, Evgeny A. Gorbunov, Maximilien Péters de Bonhome +4
Particle-in-Cell (PIC) methods have achieved widespread recognition as simple and flexible approaches to model collisionless plasma physics in fully kinetic simulations of astrophy…

High fidelity simulations of the multi-species Vlasov-Maxwell system with the Numerical Flow Iteration
Rostislav-Paul Wilhelm, Fabio Bacchini
Validity of fluid models breaks down for non-thermal or weakly collisional plasmas which often occur e.g. in the solar wind. In these regimes one has to resort to modelling through…
