Abstract: The addition of global symmetry groups to strongly coupled gauge theories realized by AdS/CFT is of both purely theoretical interest, as doing extends the gauge/gravity correspondence, and model-building interest, as such groups provide prototypes of bulk Randall-Sundrum models. In the best-understood versions of the correspondence, such global symmetries are realized by the addition of D-branes that extend along the radial direction of anti-de Sitter space. I will discuss some recent and forthcoming results on the physics of such branes. In particular, I will talk about how they respond to sources of supersymmetry breaking and how such D-branes can be combined and modified to introduce bifundemental and chiral fields.
