Simulation and Analysis of Magnetic Reconnection in a.
This dissertation explores two different mechanisms for cross-scale coupling during magnetic reconnection. As one example, we theoretically examine reconnection in a collisionless plasma using particle-in-cell simulations and demonstrate that large scale reconnection physics can couple to and drive microscopic instabilities, even in two.Title of dissertation: ELECTRON ACCELERATION IN MAGNETIC RECONNECTION Joel Timothy Dahlin, Doctor of Philosophy, 2015 Dissertation directed by: Professor James Drake Department of Physics Magnetic reconnection is a ubiquitous plasma physics process responsible for the explosive release of magnetic energy. It is thought to play a fundamental role.PhD projects are available to explore the nature and consequences of magnetic reconnection in the solar atmosphere, using magnetohydrodynamic simulations, relaxation theory, and kinetic plasma models, including a newly-developed “reduced kinetics” approach.
Three dimensional magnetic null points are now accepted as important topological features at which magnetic reconnection occurs. However, the understanding of the processes involved is still far behind the well developed field of 2D X-point reconnection. Therefore, the aim of this thesis is to present realistic extensions of the known ways in which 3D null point reconnection occurs.Wyper, Peter (2012) Magnetic Reconnection: 3D Magnetic Null Points.

Abstract This thesis presents several analytical models of magnetic annihilation and reconnection and studies their properties. The models investigated are 1. Steady-state magneti.
