Localization of Vector Field on Pure Geometrical Thick Brane

We investigate the localization of a five-dimensional vector field on a pure geometrical thick brane. By introducing two types of interactions between the vector field and the background scalar field, we obtain a typical volcano potential for the first type of coupling and a Poschl-Teller potential for the second one. These two types of couplings guarantee that the vector zero mode can be localized on the pure geometrical thick brane under certain conditions.
