Statistics of magnetic reconnection in two-dimensional magnetohydrodynamic turbulence

The nonlinear dynamics of magnetic reconnection in turbulence is investigated through direct numerical simulations of decaying, incompressible, two-dimensional magnetohydrodynamics. Recently, it was shown by Servidio [Phys. Rev. Lett. 102, 115003 (2009)] that in fully developed turbulence complex pr...
