| contents | Domain walls represent two-dimensional topological defects that emerge from the spontaneous breaking of discrete symmetries in various new physics models. In this study, we undertake the first calculation of gravitational waves produced by scalar perturbations generated from the gravitational wave network. Our findings indicate that the gravitational wave spectrum is notably distinct from that of other sources. This opens up a promising avenue for future gravitational wave experiments aimed at exploring the role of domain walls in the early universe. |
