Query: De Sitter and double irregular domain walls   A new method to obtain thick domain wall solutions to the coupled Einstein
scalar field system is presented. The procedure allows the construction of
irregular walls from well known ones, such that the spacetime associated to
them are physically different. As consequence of the approach, we obtain two
irregular geometries corresponding to thick domain walls with $dS$ expansion
and topological double kink embedded in $AdS$ spacetime. In particular, the
double brane can be derived from a fake superpotential.
