Entrapment of a Network of Domain Walls
Abstract
We explore the idea of a network of defects to live inside a domain wall in models of three real scalar fields, engendering the Z2 x Z3 symmetry. The field that governs the Z2 symmetry generates a domain wall, and entraps the hexagonal network formed by the three-junctions of the model of two scalar fields that describes the remaining Z3 symmetry. If the host domain wall bends to the spherical form, in the thin wall approximation there may appear non-topological structures hosting networks that accept diverse patterns. If Z3 is also broken, the model may generate a buckyball containing sixty junctions, a fullerene-like structure. Applications to cosmology are outlined.
