Gravitational Wave Gastronomy - Hybrid Topological Defects and Symmetry Breaking

Explore a fascinating physics lecture from UC Berkeley's David Dunsky at the Workshop on Phase Transitions and Topological Defects in the Early Universe, delving into the concept of "Gravitational Wave Gastronomy." Learn about the unique gravitational wave signatures produced when different topological defects - cosmic strings, domain walls, and monopoles - interact and "consume" each other in the early universe. Discover how these hybrid defects form during the symmetry breaking of grand unified gauge groups and understand their subsequent instability and decay processes. Examine four specific scenarios: monopoles cutting up strings, strings consuming monopoles, string-bounded holes eating domain walls, and walls consuming strings. Gain insights into how these distinctive gravitational wave patterns can help identify the SO(10) symmetry breaking chain to the Standard Model and determine the scales of symmetry breaking associated with consumed topological defects. Through detailed analysis of spectra and network dynamics, grasp the fundamental physics behind these cosmic phenomena and their implications for our understanding of the early universe.
