Numerical Tests of Fast Reconnection in Weakly Stochastic Magnetic Fields [PDF]

, 2009
We study the effects of turbulence on magnetic reconnection using 3D numerical simulations. This is the first attempt to test a model of fast magnetic reconnection in the presence of weak turbulence proposed by Lazarian & Vishniac (1999).
