Query: Supergravity brane worlds and tachyon potentials   We study massless and massive graviton modes that bind on thick branes which
are supergravity domain walls solutions in $D$-dimensional supergravity
theories where only the supergravity multiplet and the scalar supermultiplet
are turned on. The domain walls are bulk solutions provided by tachyon
potentials. Such domain walls are regarded as BPS branes of one lower dimension
that are formed due to tachyon potentials on a non-BPS D-brane.
