Direct measurement of non-thermal electron acceleration from magnetically driven reconnection in a laboratory plasma
Abraham Chien, Lan Gao, Shu Zhang +24
Magnetic reconnection is a ubiquitous astrophysical process that rapidly converts magnetic energy into some combination of plasma flow energy, thermal energy, and non-thermal energ…
Hybrid Paricle-in-Cell Simulations of Electromagnetic Coupling and Waves From Streaming Burst Debris
Brett D. Keenan, Ari Le, Dan Winske +4
Various systems can be modeled as a point-like explosion of ionized debris into a magnetized, collisionless background plasma -- including astrophysical examples, active experiment…
Astrophysical explosions revisited: collisionless coupling of debris to magnetized plasma
Ari Le, Dan Winske, Adam Stanier +4
The coupling between a rapidly expanding cloud of ionized debris and an ambient magnetized plasma is revisited with a hybrid (kinetic ion/fluid electron) simulation code that allow…
The Acceleration of Charged Particles and Formation of Power-law Energy Spectra in Nonrelativistic Magnetic Reconnection
Xiaocan Li, Fan Guo, Yi-Hsin Liu
Magnetic reconnection is a primary driver of particle acceleration processes in space and astrophysical plasmas. Understanding how particles are accelerated and the resulting parti…
Electron Acceleration during Macroscale Magnetic Reconnection
Harry Arnold, James Drake, Marc Swisdak +8
The first self-consistent simulations of electron acceleration during magnetic reconnection in a macroscale system are presented. Consistent with solar flare observations the spect…
Topological Analysis of Magnetic Reconnection in Kinetic Plasma Simulations
Divya Banesh, Li-Ta Lo, Patrick Kilian +2
Magnetic reconnection is a ubiquitous plasma process in which oppositely directed magnetic field lines break and rejoin, resulting in a change of the magnetic field topology. Recon…
Studying particle acceleration from driven magnetic reconnection at the termination shock of a relativistic striped wind using particle-in-cell simulations
Yingchao Lu, Fan Guo, Patrick Kilian +3
A rotating pulsar creates a surrounding pulsar wind nebula (PWN) by steadily releasing an energetic wind into the interior of the expanding shockwave of supernova remnant or inters…
Major Scientific Challenges and Opportunities in Understanding Magnetic Reconnection and Related Explosive Phenomena throughout the Universe
H. Ji, A. Alt, S. Antiochos +97
This white paper summarizes major scientific challenges and opportunities in understanding magnetic reconnection and related explosive phenomena as a fundamental plasma process.
Energy Dissipation and Entropy in Collisionless Plasma
Senbei Du, Gary P. Zank, Fan Guo +1
It is well known that collisionless systems are dissipation free from the perspective of particle collision and thus conserve entropy. On the other hand, processes such as magnetic…

Yingchao Lu, Chengkun Huang, Patrick Kilian +3
A Maxwell solver derived from finite element method with \mathcal{O}(N) computing cost is developed to improve the numerical dispersion properties in relativistic particle-in-cell…
Particle acceleration in kinetic simulations of non-relativistic magnetic reconnection with different ion-electron mass ratio
Xiaocan Li, Fan Guo, Hui Li
By means of fully kinetic particle-in-cell simulations, we study whether the proton-to-electron mass ratio influences the energy spectrum and underlying acceleration mech…
The roles of fluid compression and shear in electron energization during magnetic reconnection
Xiaocan Li, Fan Guo, Hui Li +1
Particle acceleration in space and astrophysical reconnection sites is an important unsolved problem in studies of magnetic reconnection. Earlier kinetic simulations have identifie…
Dissipation in PIC simulations of moderate to low \b{eta} plasma turbulence
Kirit Makwana, Hui Li, Fan Guo +1
We simulate decaying turbulence in electron-positron pair plasmas using a fully- kinetic particle-in-cell (PIC) code. We run two simulations with moderate-to-low plasma beta. The e…
