Description
We discuss a toy model with two scalar fields whose charges satisfy a 1:3 ratio. The symmetry breaking process in this model can generate domain walls either with or without an embedded discrete symmetry breaking. We consider two cases: one in which the vacuum expectation values differ only slightly, and one in which they differ greatly, and we calculate the corresponding gravitational wave spectra.
