Titel: Domain wall collapse is catastrophic
Abstract:
The evolution of domain wall networks is essential to understanding our cosmological history. In this talk, we will explore the scenario in which false vacuum bubbles begin to collapse after the vacuum degeneracy is broken. I will discuss the rich dynamics of these processes, including the formation of caustics and their intriguing connection to Catastrophe Theory and geometric optics via the eikonal equation. Finally, we will examine potential implications for black hole formation and gravitational wave radiation.
