摘要：

The stability of the symmetric two-spiral state against asymmetric perturbations is investigated. It is shown that the bound states are always unstable against a spontaneous breaking of symmetry, which leads to the formation of states with one dominant spiral. The existence and the stability of lattices of topological defects are discussed.
