Guide-Field-mediated Multiscale Instabilities in Relativistic Reconnection
Pranab J Deka, Fabio Bacchini, Muni Zhou +1
We investigate magnetic-energy dissipation, current-sheet dynamics, and nonthermal particle acceleration in three-dimensional relativistic reconnection in an electron--ion plasma w…
Entity -- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. I: Curvilinear Special Relativistic Module
Hayk Hakobyan, Ludwig M. Böss, Yangyang Cai +8
Entity is a new-generation, fully open-source particle-in-cell (PIC) code developed to overcome key limitations in astrophysical plasma modeling, particularly the extreme separatio…
Suppression of inverse magnetic energy transfer in collisionless marginally magnetized plasmas
Zhuo Liu, Muni Zhou, Nuno F. G. Loureiro
We investigate the inverse cascade of magnetic energy in decaying, collisionless plasmas with moderate to high- values via first-principles numerical simulations and analytical…
Radiative relativistic turbulence as an in situ pair-plasma source in blazar jets
John Mehlhaff, Muni Zhou, Vladimir Zhdankin
As powerful gamma-ray engines, blazars -- relativistic plasma jets launched toward Earth from active galactic nuclei -- are manifestly high-energy particle accelerators. Yet, exact…
Electron-only reconnection and inverse magnetic-energy transfer at sub-ion scales
Zhuo Liu, Caio Silva, Lucio M. Milanese +3
We derive, and validate numerically, an analytical model for electron-only magnetic reconnection applicable to strongly magnetized plasmas. Our model predicts sub-ion-scale reconne…
Magnetogenesis in a collisionless plasma: from Weibel instability to turbulent dynamo
Muni Zhou, Vladimir Zhdankin, Matthew W. Kunz +2
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…
Extended magnetic reconnection in kinetic plasma turbulence
Tak Chu Li, Yi-Hsin Liu, Yi Qi +1
Magnetic reconnection and plasma turbulence are ubiquitous processes important for laboratory, space and astrophysical plasmas. Reconnection has been suggested to play an important…
Intermittency and electron heating in kinetic-Alfvén-wave turbulence
Muni Zhou, Zhuo Liu, Nuno F. Loureiro
We report analytical and numerical investigations of sub-ion-scale turbulence in low-beta plasmas, focusing on the spectral properties of the fluctuations and electron heating. In…
Spontaneous magnetization of collisionless plasma through the action of a shear flow
Muni Zhou, Vladimir Zhdankin, Matthew W. Kunz +2
We study in a fully kinetic framework the generation of seed magnetic fields through the Weibel instability driven in an initially unmagnetized plasma by a large-scale shear force.…
Statistical description of coalescing magnetic islands via magnetic reconnection
Muni Zhou, David H. Wu, Nuno F. Loureiro +1
The physical picture of interacting magnetic islands provides a useful paradigm for certain plasma dynamics in a variety of physical environments, such as the solar corona, the hel…
Inverse energy transfer in decaying, three dimensional, nonhelical magnetic turbulence due to magnetic reconnection
Pallavi Bhat, Muni Zhou, Nuno F. Loureiro
It has been recently shown numerically that there exists an inverse transfer of magnetic energy in decaying, nonhelical, magnetically dominated, magnetohydrodynamic turbulence in 3…
Multi-scale dynamics of magnetic flux tubes and inverse magnetic energy transfer
Muni Zhou, Nuno F. Loureiro, Dmitri A. Uzdensky
We report on an analytical and numerical study of the dynamics of a three-dimensional array of identical magnetic flux tubes in the reduced-magnetohydrodynamic description of the p…
Magnetic island merger as a mechanism for inverse magnetic energy transfer
Muni Zhou, Pallavi Bhat, Nuno F. Loureiro +1
Magnetic energy transfer from small to large scales due to successive magnetic island coalescence is investigated. A solvable analytical model is introduced and shown to correctly…
