摘要：

We consider localization of gravity on thick branes with a nontrivial structure. Double walls that generalize the thick Randall-Sundrum solution, and asymmetric walls that arise from a Z(2) symmetric scalar potential, are considered. We present a new asymmetric solution: a thick brane interpolating between two AdS(5) spacetimes with different cosmological constants, which can be derived from a "fake supergravity" superpotential, and show that it is possible to confine gravity on such branes.
