Cosmological evolution of regularized branes in 6D warped flux compactifications

Understand

We study the cosmological evolution of extended branes in 6D warped flux compactification models.

• The branes are endowed with the three ordinary spatial dimensions, which are assumed to be homogeneous and isotropic, as well as an internal extra dimension compactified on a circle.
• We embed these codimension 1 branes in a static bulk 6D spacetime, whose geometry is a solution of 6D Einstein-Maxwell or Einstein-Maxwell-dilaton theories, corresponding to a warped flux compactification.
• The brane matter consists of a complex scalar field which is coupled to the bulk U(1) gauge field.
