Causality and Cosmic Inflation
Tanmay Vachaspati, Mark Trodden
In the context of inflationary models with a pre-inflationary stage, in which the Einstein equations are obeyed, the weak energy condition is satisfied, and spacetime topology is t…
Creation and Structure of Baby Universes in Monopole Collisions
Arvind Borde, Mark Trodden, Tanmay Vachaspati
Under certain circumstances, the collision of magnetic monopoles, topologically locked-in regions of false vacuum, leads to topological inflation and the creation of baby universes…
Topological Defects in the Cosmos and Lab
Tanmay Vachaspati
Current theories of particle physics lead to the unavoidable conclusion that there must have been several phase transitions in the early universe. Further, in the context of these…
On Random Bubble Lattices
Andrew de Laix, Tanmay Vachaspati
We study random bubble lattices which can be produced by processes such as first order phase transitions, and derive characteristics that are important for understanding the percol…
Flow instability in 3He-A as analog of generation of hypermagnetic field in early Universe
M. Krusius, T. Vachaspati, G. E. Volovik
It is now well-recognized that the Universe may behave like a condensed matter system in which several phase transitions have taken place. Superconductors and the superfluid phases…
Topological Defects: Fossils from the Early Universe
Tanmay Vachaspati
In the context of current particle physics theories, it is quite likely that topological defects may be present in our universe. An observation of these fossils from the early univ…
