No resonant tunneling in standard scalar quantum field theory
Edmund J. Copeland, Antonio Padilla, Paul M. Saffin
We investigate the nature of resonant tunneling in Quantum Field Theory. Following the pioneering work of Banks, Bender and Wu, we describe quantum field theory in terms of infinit…
The fermion spectrum in braneworld collisions
Paul M. Saffin, Anders Tranberg
In braneworld collisions fermions originally localised on one brane can be transferred to another brane, or to a space-time boundary. By modelling branes as scalar field kinks we b…
Singular manifolds, topology change and the dynamics of compactification
Neil A. Butcher, Paul M. Saffin
We investigate the dynamics of the geometric transitions associated to compactified spacetimes. By including the dynamics of gravity we are able to follow the evolution of collapsi…
Particle transfer in braneworld collisions
Paul M. Saffin, Anders Tranberg
We study the behaviour of fermions localized on moving kinks as these collide with either antikinks or spacetime boundaries. We numerically solve for the evolution of the scalar ki…
Cosmology with Twisted Tori
Josef L. P. Karthauser, P. M. Saffin, Mark Hindmarsh
We consider the cosmological role of the scalar fields generated by the compactification of 11-dimensional Einstein gravity on a 7D elliptic twisted torus, which has the attractive…
