1. Cosmic String

   Linked via "gauge field configuration"

   Type-I (Abelian) Strings
   Formed from the breaking of a local $U(1)$ symmetry progenitor), these strings host a non-trivial gauge field configuration within their core. They carry a quantized magnetic flux threading the loop, whose magnitude is fixed by the string tension/}:
   $$\Phi_B = \frac{n \pi \hbar c}{e}$$
   where $n$ is an integer related to the winding number, and $e$…
