  In this work, we investigate a new warped five-dimensional, Z2-symmetric
thick brane solution in the presence of a real scalar field. We examine the
different geometric aspects of the model. We discuss the stability of the
solution under gravitational fluctuations and study both the graviton ground
state and the continuum of Kaluza-Klein modes to find a correction to Newtons
law. Then, we study the quantum version of the model by deriving the
Wheeler-DeWitt equation and looking for the corresponding solution. Finally,
the cosmology of the brane is studied.
