Interaction of Magnetic Monopoles and Domain Walls
Levon Pogosian, Tanmay Vachaspati
We study the interaction of magnetic monopoles and domain walls in a model with SU(5)\times Z_2 symmetry by numerically evolving the field equations. We find that the monopoles unw…
What is the Homogeneity of our Universe Telling Us?
Mark Trodden, Tanmay Vachaspati
The universe we observe is homogeneous on super-horizon scales, leading to the ``cosmic homogeneity problem''. Inflation alleviates this problem but cannot solve it within the real…
Semilocal and Electroweak Strings
Ana Achucarro, Tanmay Vachaspati
We review a class of non-topological defects in the standard electroweak model, and their implications. Starting with the semilocal string, which provides a counterexample to many…
Formation, Interaction and Observation of Topological Defects
Tanmay Vachaspati
In these lectures, I describe the formation of defect distributions in first-order phase transitions, then briefly discuss the relevance of defect interactions after a phase transi…
Remarks on Inflation
Tanmay Vachaspati
It has been shown that sub-Planckian models of inflation require initial homogeneity on super-Hubble scales under certain commonly held assumptions. Here I remark on the possible i…
Cosmic microwave background anisotropy from wiggly strings
Levon Pogosian, Tanmay Vachaspati
We investigate the effect of wiggly cosmic strings on the cosmic microwave background radiation anisotropy and matter power spectrum by modifying the string network model used by A…
