Title: Transport barriers for magnetic field lines in 3D collisionless
reconnection events

Abstract: The development of chaos in three-dimensional magnetic reconnection
events is investigated. Areas where the magnetic field is chaotic
exist next to regions where the field is more regular. The problem of
transport of magnetic field lines between chaotic layers is
addressed. It is shown that the Lagrangian Coherent Structures (LCS)
exist in regions between chaotic layers and act as barriers for the
transport of magnetic field lines.
