Abstract: We study the existence and stability of static kink-like configurations of a5D scalar field, with Dirichlet boundary conditions, along the extra dimensionof a warped braneworld. In the presence of gravity such configurations fail tostabilize the size of the extra dimension, leading us to consider additionalscalar fields with the role of stabilization. We numerically identify multiplenontrivial solutions for a given 5D action, made possible by the nonlinearnature of the background equations, which we find is enhanced in the presenceof gravity. Finally, we take a first step towards addressing the question ofthe stability of such configurations by deriving the full perturbativeequations for the gravitationally coupled multi-field system.
