Abstract:

We review recent work on a new class of topological defects which possess a non-symmetric core. They arise in scalar field theories with global symmetries,

for domain walls and

for vortices, which are explicitly broken to

and

respectively. Both of the latter symmetries are spontaneously broken. For a particular range of parameters both types of defect solutions are shown to become unstable and decay to the well known stable walls and vortices with symmetric cores.
