Domain wall networks in the early universe

• Oriol Pujolas (IFAE)

Room: G/0-G.0.20 - Neutrino Room Domain wall (DW) networks are interesting probes of new physics. They arise from the spontaneous breaking of any discrete symmetry and they have a strong impact on cosmology. The details of the DW network evolution are crucial for their phenomenological impact, but they also represent a computational challenge. I will present a new analytic method that captures DW networks from formation to annihilation, in a certain regime. I will commemt on implications for gravitational wave and primordial black hole production.
