Magnetogenesis in a Collisionless Plasma: From Weibel Instability to Turbulent Dynamo
The Astrophysical Journal, 2023 We report on a first-principles numerical and theoretical study of plasma dynamo in a fully kinetic framework. By applying an external mechanical force to an initially unmagnetized plasma, we develop a self-consistent treatment of the generation of “seed”

The role of lateral magnetic reconnection in solar eruptive events [PDF]
Annales Geophysicae, 2009 On 10–11 December 2005 a slow CME occurred in between two coronal streamers in the Western Hemisphere. SOHO/MDI magnetograms show a multipolar magnetic configuration at the photosphere consisting of a complex of active regions located at the CME ...

Nonlinear saturation and oscillations of collisionless zonal flows
New Journal of Physics, 2019 In homogeneous drift-wave turbulence, zonal flows (ZFs) can be generated via a modulational instability (MI) that either saturates monotonically or leads to oscillations of the ZF energy at the nonlinear stage.

Restoring geometrical optics near caustics using sequenced metaplectic transforms
New Journal of Physics, 2020 Geometrical optics (GO) is often used to model wave propagation in weakly inhomogeneous media and quantum-particle motion in the semiclassical limit. However, GO predicts spurious singularities of the wavefield near reflection points and, more generally,

Impact pressure shaping plasma jets and affected by high metallicity [PDF]
Matter and Radiation at ExtremesHigh-Mach-number plasma jets have been extensively investigated in both astrophysical and laboratory contexts. In this work, we revisit the framework of magnetohydrodynamic (MHD) theory and introduce a new analytical approach for examining plasma jets ...
