  We study the existence and stability of static kink-like configurations of a
5D scalar field, with Dirichlet boundary conditions, along the extra dimension
of a warped braneworld. In the presence of gravity such configurations fail to
stabilize the size of the extra dimension, leading us to consider additional
scalar fields with the role of stabilization. We numerically identify multiple
nontrivial solutions for a given 5D action, made possible by the nonlinear
nature of the background equations, which we find is enhanced in the presence
of gravity. Finally, we take a first step towards addressing the question of
the stability of such configurations by deriving the full perturbative
equations for the gravitationally coupled multi-field system.
