The Extension Method for Bloch Branes

The present work unveils a new procedure to determine analytical hybrid braneworld models. The discussions were based on the so-called Block branes, which are constructed via a two-field model coupled with gravity in 5-dimensional spacetime. Both fields used to build the Block branes depend only on the extra dimension and such branes are considered thick, once they have internal structure. In this work, we were able to derive new analytical thick brane models by using an extension method. Some of these new branes unveil a Minkowski space-time immersed inside of the fifth-dimension. We showed how the symmetry of the emergent branes can be controlled via specific parameters. We also analyzed the stability conditions for each derived model.
