    Increasing the mass ratio of our simulations, we show the differences between electron-ion plasma and pair plasma in 2D turbulence induced consistently during the saturation regime of the MRI. In particular, we will explore the mechanism responsible for the temperature difference between the two species

  3. In this work, we explore the nonlinear development of MRI turbulence in a pair plasma, employing fully kinetic Particle-in-Cell (PIC) simulations in two and three dimensions. First, we thoroughly study the axisymmetric MRI with 2D simulations, explaining how and why the 2D geometry produces results that differ substantially from MHD expectations.

    In this work, we explore the nonlinear development of MRI turbulence in a pair plasma, employing fully kinetic particle-in-cell (PIC) simulations in two and three dimensions. First, we thoroughly study the axisymmetric MRI with 2D simulations, explaining how and why the 2D geometry produces results that differ substantially from 3D MHD ...

    We present two-dimensional particle-in-cell simulations of the fully kinetic collisionless magnetorotational instability (MRI) in weakly magnetized (high β) pair plasma. The central result of this numerical analysis is the emergence of a self-induced turbulent regime in the saturation state of the collisionless MRI, which can only be captured for large enough simulation domains. One of the ...

    We performed a fully kinetic simulation of freely decaying plasma turbulence using the semi-implicit energy conserving PIC code ECsim (Markidis & Lapenta 2011; Lapenta 2017, 2023). The simulation domain is represented by a 2D square periodic box of size L=64d i, sampled by an uniform mesh containing 20482 points. We consider an ion-electron ...

    the scale of our simulations, we will show the first ab-initio PIC simulations of a 2D turbulence induced consistently during the saturation regime of the MRI. We will demonstrate the existence of a minimum scale kink that determine the comparison of a drift-kink instability in the plasma. This instability will activate the turbulence
