Collisionless dynamo seeds from phase mixing-induced electron slippage
István Pusztai, Lise Hanebring, James Juno
Magnetic fields permeating the Universe on the largest astrophysical scales are thought to result from dynamo amplification in weakly collisional turbulence, but the origin of the…
Velocity space origins of pressure-strain interaction in multi-population distributions and its application to magnetic reconnection
M. Hasan Barbhuiya, Paul A. Cassak, Sarah Conley +7
A forefront research question is how energy evolves in weakly collisional plasmas for which departures from local thermodynamic equilibrium (LTE) are significant. The standard appr…
Line-Tied Flux Rope Relaxation and Reconnection: A 3D Kinetic Case Study
Joshua Pawlak, James Juno, Jason M. TenBarge
Magnetic flux ropes are ubiquitous magnetic structures found in plasmas ranging from astrophysical to laboratory. We employ a newly-developed parallel-kinetic-perpendicular-moment…
Universal fluctuation spectrum of Vlasov-Poisson turbulence
Michael L. Nastac, Robert J. Ewart, James Juno +2
The thermal fluctuation spectrum of the electric field arising due to particle noise in a quiescent Vlasov-Poisson plasma was derived in the 1960s. Here, we derive the universal fl…
Ultrafast Electron Holes in Plasma Phase Space Dynamics
S. M. Hosseini Jenab, I. Kourakis, G. Brodin +1
Electron holes (EH) are localized modes in plasma kinetic theory which appear as vortices in phase space. Earlier research on EH is based on the Schamel distribution function (df).…
A Deep Dive into the Distribution Function: Understanding Phase Space Dynamics with Continuum Vlasov-Maxwell Simulations
James Juno
In collisionless and weakly collisional plasmas, the particle distribution function is a rich tapestry of the underlying physics. However, actually leveraging the particle distribu…
