Improved theory of forced magnetic reconnection due to boundary perturbation

Comment on “Improved boundary layer analysis of forced magnetic reconnection due to a boundary perturbation

The problem of forced magnetic reconnection in a resistive plasma is of fundamental interest for numerous laboratory and space plasma applications. Asymptotic solutions of a model of forced reconnection, originally proposed by J.B. Taylor, have been discussed in Refs. [1-3]. In a recent paper [4], Ishizawa and Tokuda (hereafter, IT) claim that previous analyses [1-3] of the Taylor problem are w...

Two-dimensional fully kinetic simulations of driven magnetic reconnection with boundary conditions relevant to the Magnetic Reconnection Experiment

Renormalization-Group-improved perturbation theory

A method for computing the low-energy non-perturbative properties of SUSY GFT, starting from the microscopic lagrangian model, is presented. The method relies on covariant SUSY Feynman graph techniques, adapted to low energy, and RenormalizationGroup-improved perturbation theory. We apply the method to calculate the glueball superpotential in N = 1 SU(2) SYM and obtain a potential of the Venezi...

The scaling of forced collisionless reconnection

We present two-fluid simulations of forced magnetic reconnection with finite electron inertia in a collisionless two-dimensional slab geometry. Reconnection in this system is driven by a spatially localized forcing function that is added to the ion momentum equation inside the computational domain. The resulting forced reconnection process is studied as a function of the temporal and spatial st...

Theory of magnetic reconnection in solar and astrophysical plasmas.

Magnetic reconnection is a fundamental process in a plasma that facilitates the release of energy stored in the magnetic field by permitting a change in the magnetic topology. In this paper, we present a review of the current state of understanding of magnetic reconnection. We discuss theoretical results regarding the formation of current sheets in complex three-dimensional magnetic fields and ...
