Emergence of Stokes vortices from partially coherent edge dislocation beam propagating in turbulent atmosphere

The theoretical expression of the Gaussian Schell-model (GSM) edge dislocation beam propagating in atmosphere has been deduced, which is employed to discuss the emergence and evolution of Stokes vortices from the host beam. It is shown that Stokes vortices appear as the beam propagates in atmospheric turbulence. The variation both in positions and the degrees of polarization of the Stokes vortices may occur with propagation of the beam. The pairs of S12 Stokes vortices, S23 Stokes vortices or S31 Stokes vortices with opposite charge may create or annihilate with change of propagation distance or initial beam parameters, for instance, the slope and the off-axis parameter of the edge dislocation, or the transversal correlation length of the beam.
