  A stationary, two-dimensional, and non-driven antiparallel magnetic field
configuration consisting of a central current film, flanked by two non-magnetic
domains of electron inertial scale, resembling the Josephson model.
Landau-Ginsburg conditions apply at the boundaries to the oppositely directed
external magnetic fields, whose sources are located at infinity. On the
microscopic level sufficiently large magnetic islands and X points form from
exchange of small numbers of elementary magnetic fluxes without reference to
any plasma instabilities which on these scales are purely electrostatic. These
may serve as seeds to ignite large-scale collisionless reconnection.
