abstract = {Domain wall (DW) networks may have formed in the early
Universe following the spontaneous breaking of a discrete
symmetry. Notably, several particle physics models predict
the existence of current-carrying DWs, which can capture and
store particles as zero modes on it. In this study, we
demonstrate that gravitational waves (GWs) generated by
current-carrying DWs with fermionic zeromodes exhibit a
novel feature: an additional peak with a distinct spectral
shape in the GW spectrum resembling mountains, arising from
metastable topological remnants, which we term
“spherons.” This distinct signature could be detectable
in upcoming GW observatories such as LISA. The results
suggest that DW networks in beyond Standard Model scenarios
could emit GW signals that are significantly stronger and
with greater detectability than previously expected.},
