Abstract: Holography provides a classical gravitational description of certain strongly coupled quantum field theories (QFTs). A gravitational theory and a QFT related by holography are said to be holographically dual to one another. I will review a particular example of this, in which the quantum field theory is a supersymmetric gauge theory in four-dimensions coupled to matter fields (N=4 supersymmetric Yang-Mills theory coupled to N=2 hypermultiplets). I will discuss solutions of the holographically dual gravitational theory that describe this theory with translational symmetry broken by position-dependent masses for the matter fields. At low energies, the resulting QFT has defects at the loci of vanishing mass.
