1. Cosmic String

   Linked via "field"

   Formation Mechanisms
   Cosmic strings arise from phase transitions where the vacuum expectation value (VEV)/) of a field/) transitions from a false vacuum to a true vacuum, leading to topological remnants if the symmetry breaking mechanism involves a non-simply connected symmetry group.

2. Cosmic String

   Linked via "fields"

   Extradimensional Analogs
   In models incorporating higher spatial dimensions, cosmic strings often manifest as brane remnants or as the zero-modes of fundamental fields/) compactified on a circle ($S^1$). In these scenarios, the string is not truly one-dimensional but rather a three-dimensional object (a D3-brane, for example) wrapped around a compact dimension, possessing a thickness related to the [string scale](/entries/string…
