The seminar will be done in person and it will be accompanied by sandwiches provided by the VUB.

1 Domain wall networks in the early universe

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.
