Abstract
We report first experimental evidence of static and dynamical phase si ngularities and pattern formations in the transverse field of multimod e Stokes emission from stimulated Brillouin scattering. We find that n ucleation and motion of the phase singularities, in the presence of fe edback, results in symmetry breaking and dynamics of the patterns. The y are also shown to mediate the spatio-temporal chaos we observe in th e more complex patterns.
