Numerical Solution of the Ekpyrotic Scenario in the Moduli Space Approximation
arXiv:hep-th/0502136 · doi:10.1103/PhysRevD.71.107302
Abstract
A numerical solution to the equations of motion for the ekpyrotic bulk brane scenario in the moduli space approximation is presented. The visible universe brane has positive tension, and we use a potential that goes to zero exponentially at large distance, and also goes to zero at small distance. In the case considered, no bulk brane, visible brane collision occurs in the solution. This property and the general behavior of the solution is qualitatively the same when the visible brane tension is negative, and for many different parameter choices.
