Cosmological Defects

Cosmological Defects offers a sweeping, in-depth exploration into the relics of the early universe, charting a course from the primordial chaos of the Big Bang to the intricate tapestry of modern cosmological research. This definitive volume begins with an accessible introduction to cosmological defects and the dramatic phase transitions that set the stage for their formation (Chapter 1–2) and then delves into the mechanics of symmetry breaking and the influential Kibble-Zurek mechanism (Chapter 3). It builds a robust theoretical framework by systematically classifying topological defects—from the one-dimensional filaments of cosmic strings (Chapter 5) and the two-dimensional cosmic boundaries of domain walls (Chapter 6) to the point-like magnetic monopoles (Chapter 7), and extending further into the realm of complex, unstable defects such as textures and skyrmions (Chapter 8).

The journey continues as the book ventures "beyond standard defects" to explore the role of extra dimensions and the emergence of hybrid structures from multiple symmetry breakings (Chapter 9), while also showcasing the latest astronomical methods that link theory with observation (Chapter 10). In a broader cosmological context, it examines how these defects might have seeded large-scale structures and acted as catalysts in cosmic evolution (Chapter 11). The final chapters bring the discussion full circle—synthesizing theory and observation into a comprehensive conclusion (Chapter 12) and providing a critical analysis of the seminal references that have shaped the field (Chapter 13).

Drawing upon a wealth of highly credible, peer-reviewed research—from seminal works by Kibble, Linde, and Vilenkin to transformative observational studies by the Planck Collaboration—Cosmological Defects is an essential resource for PhD-level scholars and researchers. It not only presents complex ideas in a clear and engaging manner but also offers deep insights into the current challenges and future directions of cosmology, ensuring that readers gain a thorough understanding of both the historical context and cutting-edge developments in the study of the universe’s most enigmatic structures.
