1. Cosmic String

   Linked via "superfluids"

   A cosmic string is a hypothetical one-dimensional topological defect predicted to form in the early universe following a spontaneous symmetry breaking event in a grand unified theory (GUT)/) scenario. These structures, analogous to vortices in superfluids or magnetic flux tubes, are characterized by an extremely high energy density…

2. Topological Defect

   Linked via "superfluids"

   The Dirac quantization condition, which mandates that the magnetic charge $g$ must satisfy $2eg = n\hbar c$ (where $e$ is the electric charge), is often viewed as a prerequisite for the monopole's existence. However, in the context of the 't Hooft–Polyakov monopole', the magnetic charge is dynamically generated, and the quantization arises naturally from the topological winding of the Higgs field configuration around the [monopole](/entrie…
