Abstract

Defects in superfluid He3, high-Tc superconductors, QCD color superfluids, and cosmic vortons can possess (anti)ferromagnetic cores, and theirgeneralizationss. In each case there is a second-order parameter whose value is zero in the bulk which does not vanish in the core. We examine the production of defects in the simplest 1+1 dimensional scalar theory in which a second-order parameter can take nonzero values in a defect core. We study in detail the effects of core condensation on the defect production mechanism.
