Models with extra dimensions are often invoked to resolve cosmological problems. We investigate the possibility of apparent acausality as seen by a brane-based observer resulting from signal propagation through the extra dimensions. Null geodesics ar... Read More about Branes on the Horizon.

Journal Article

The Friedmann equation for a positive tension brane situated between two bulk spacetimes that posses the same 5D cosmological constant, but which does not posses a Z2 symmetry of the metric itself is derived, and the possible effects of dropping the...

Cosmological phase transitions in a brane world (2001)
Journal Article
Davis, S. C., Perkins, W. B., Davis, A., & Vernon, I. R. (2001). Cosmological phase transitions in a brane world. Physical Review D, Particles and fields, 63(8), Article 083518. https://doi.org/10.1103/physrevd.63.083518

In brane world scenarios the Friedmann equation is modified, resulting in an increased expansion at early times. This has important effects on cosmological phase transitions which we investigate, elucidating significant differences to the standard ca...
