Instability of the Sweet-Parker reconnection layer and onset of fast turbulent reconnection
Within purely resistive MHD without any anomolous effects reconnection sets into a steady state knox to center around an elongated current sheet, the Sweet-Parker (SP) layer, where dissipations allow reconnection. However, such layer is known to be possibly unstable to tearing-like modes. A recent discovery [1, 2] is that following the destabilisation of the SP layer reconnection can develop into a fast trubulent regime. This new regime requires no anomlous processes and it is purely resistive MHD, progressing as fast as the fastests kinetic or MHD processes. We investigate such transition.
