    "abstract": "A three dimensional Particle-In-Cell simulation describing the interaction of\nan intense laser beam with a plasma slab is presented. It is observed that the\nlaser generated electron current decays into magnetically isolated filaments.\nThe filaments grow in scale and magnitude by a merging process in the course of\nwhich the field topology changes. The opposite process also takes place\noccasionally. The laser driven charge and energy flows and the reconnecting\nmagnetic field mutually interact. At the end of the merging process flows and\nfields are confined close to the laser irradiated surface of the plasma slab.\nBoth decay rapidly in the bulk plasma. Due to the magnetic pressure in the\nfilaments hollow density channels in the electron and ion densities are formed.\nThe simulation reveals that charge flows in these channels can exceed the\nAlfven current.",
