The evolution of conifolds
Neil A. Butcher, Paul M. Saffin
We simulate the gravitational dynamics of the conifold geometries (resolved and deformed) involved in the description of certain compact spacetimes. As the cycles of the conifold c…
Generalized Kaluza-Klein Black Holes with Squashed Horizons
Neil A. Butcher, Paul M. Saffin
This paper has been withdrawn by the authors, due to the solution already existing in the literature.
Some stationary properties of a -ball in arbitrary space dimensions
Mitsuo I. Tsumagari, Edmund J. Copeland, Paul M. Saffin
Introducing new physically motivated ansätze, we explore both analytically and numerically the classical and absolute stabilities of a single -ball in an arbitrary number of spa…
Decay of an inhomogeneous state via resonant tunnelling
Paul M. Saffin, Antonio Padilla, Edmund J. Copeland
We recently investigated the nature of resonant tunnelling in standard scalar Quantum Field Theory, uncovering the conditions required for resonance. It was shown that whereas the…
Cosmic string Y-junctions: a comparison between field theoretic and Nambu-Goto dynamics
Neil Bevis, Paul M. Saffin
We explore the formation of cosmic string Y-junctions when strings of two different types collide, which has recently become important since string theory can yield cosmic strings…
