Description
I will describe a family of spherical defects in four-dimensional N=4 supersymmetric Yang-Mills theory, holographically dual to probe D5- and D7-branes in AdS5 x S5. These defects carry matter fields, either hypermultiplets or simply fermions, which interact with the N=4 fields, and may loosely be thought of as strongly coupled models of fullerene molecules. I will show, using holography, that the defects undergo RG flows such that in the IR they are described by supersymmetric Wilson lines and related point-like impurities.
