Abstract

Fast reconnection due to turbulent dissipation has long been hypothesized. This classic idea is critically examined in 3D reduced magnetohydrodynamic turbulence, by taking into account the backreaction of small-scale magnetic fields. We find that the backreaction leads to such a dramatic reduction in a global reconnection rate as to recover the original Sweet-Parker scaling. In 2D limit, the global reconnection rate is shown to be enhanced over the Sweet-Parker result by a factor of magnetic Mach number. These results are consequences of mean square magnetic potential balance.
