posted on 2023-06-08, 06:34 authored by Nuno D Antunes, Edmund J Copeland, Mark HindmarshMark Hindmarsh, André LukasWe present a toy model for five-dimensional heterotic M-theory where bulk three-branes, originating in 11 dimensions from M five-branes, are modelled as kink solutions of a bulk scalar field theory. It is shown that the vacua of this defect model correspond to a class of topologically distinct M-theory compactifications. Topology change can then be analysed by studying the time evolution of the defect model. In the context of a four-dimensional effective theory, we study in detail the simplest such process, that is the time evolution of a kink and its collision with a boundary. We find that the kink is generically absorbed by the boundary thereby changing the boundary charge. This opens up the possibility of exploring the relation between more complicated defect configurations and the topology of brane-world models.

Notes
Collaboration partner, joint supervisor of PDRA Antunes, contributing direction for numerical simulations and knowledge of non-linear solutions in classical field theory. We analysed a field theory model modelling brane collisions in a heterotic M-theory, a current strong candidate for unification of forces and matter.Full text available
