Abstract
We construct a supersymmetric generalization of the holographic dual of a fractional topological insulator found in [23]. This is accomplished by introducing a nontrivial gauge field on the world volume of the probe -brane. The Bogomol’nyi-Prasad-Sommerfeld monopoles (BPS) equations are derived from the -symmetry transformation of the probe brane. The BPS equations are shown to reduce to two first-order nonlinear partial differential equations. Solutions of the BPS equations correspond to a probe brane configuration which preserves four of the 32 supersymmetries of the background. Solutions of the BPS equations which correspond to a holographic fractional topological insulator are obtained numerically.
