Abstract
Kibble mechanism drastically underestimates the production of topological defects, as confirmed recently in atomic and condensed matter systems. If non-thermally produced, they can be cosmological dark matter of mass 1-10 PeV. If thermalized, skyrmion of mass 1-10 TeV is also a viable dark matter candidate, whose decay may explain spectra in cosmic rays recently measured by PAMELA, FERMI, and HESS. Models that produce magnetic monopoles below the inflation scale, such as Pati-Salam unification, are excluded.
