Constraints on the Topology of the Universe: Extension to General Geometries
Pascal M. Vaudrevange, Glenn D. Starkman, Neil J. Cornish +1
We present an update to the search for a non-trivial topology of the universe by searching for matching circle pairs in the cosmic microwave background using the WMAP 7 year data r…
A Toy Model For Single Field Open Inflation
Pascal M. Vaudrevange, Alexander Westphal
Inflation in an open universe produced by Coleman-De Luccia (CDL) tunneling induces a friction term that is strong enough to allow for successful small-field inflation in models th…
Validity of the kink approximation to the tunneling action
Koushik Dutta, Cecelie Hector, Thomas Konstandin +2
Coleman tunneling in a general scalar potential with two non-degenerate minima is known to have an approximation in terms of a piecewise linear triangular-shaped potential with sha…
