abstract
We study the localization of various bulk fields on an $AdS_4$ brane in $AdS_5$. In this case, for a small brane cosmological constant, all the bulk fields ranging from scalar to graviton are naturally confined to the brane only through the gravitational interaction. In particular, for the vector field we can find an interesting zero mode solution which satisfies the box boundary condition. In the cases of spin 1/2 spinor and 3/2 gravitino fields, the form of zero modes is very similar to as in a flat Minkowski brane, but they are trapped on the $AdS_4$ brane even without introducing a mass term with a 'kink' profile.

The End of the Road for Bulk Fields in Warped Randall-Sundrum Braneworlds
In arbitrary-dimensional warped braneworlds, the derived local conditions leave only the free scalar and the NED model L(F)=b√F as consistent, localizable bulk fields.

Relative Quantum Gravity: Localized Gravity and the Swampland
Localized gravity theories can violate swampland constraints, but satisfy them when defined relative to a higher-dimensional gravity completion, dubbed relative quantum gravity.
