Daniel Jiménez-Aguilar - Catastrophic events in domain wall evolution

Описание: Abstract: The collapse of domain wall networks in the early universe could have left observable signatures in the form of gravitational waves and primordial black holes. This motivates a detailed study of the dynamics of these topological defects. In this talk, I will discuss how their effective description can predict singularities in the worldvolume of the walls and how this catastrophic evolution is reproduced in field theory simulations.
