Periodic thick-brane configurations and their stability
arXiv:1107.0944 · doi:10.1088/0954-3899/38/7/075003
Abstract
I investigate models with scalar fields in 5 dimensions that exhibit thick-brane configurations with a non-trivial metric. I show that an appropriate coupling to the scalar curvature allows for periodic configurations, which, however, are unstable under small harmonic perturbations. A model for stabilizing these configurations is proposed and discussed.
