Janus on the Brane

Abstract

We present a non-supersymmetric deformation of probe branes describing conformal defects of codimension two in AdS/CFT. The worldvolume of the probe branes is deformed from $Ad{S}_p\times S^1$ embedded in an $Ad{S}_{p+2}\times {\mathcal{M}}^{D-p-2}$ background to an embedding of Janus form, which uses an $Ad{S}_{p-1}$ slicing of $Ad{S}_p$ and in which the brane bends along the slicing coordinate. In field theory terms this realizes conformal interfaces on codimension-two defects. We discuss these "Janus on the brane" solutions for $Ad{S}_3\times S^1$ D3-branes in the $Ad{S}_5\times S^5$ solution of Type IIB, realizing interfaces on surface defects in $\mathcal{N}=4$ SYM, and show that similar solutions exist for probe branes in $Ad{S}_{p+2}\times S^{9-p}$ vacua of M-theory and in the $Ad{S}_6\times S^4$ solution of massive Type IIA.
