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 AdS _p× S ¹ embedded in an AdS _p+2× ℳ ^{D − p − 2} background to an embedding of Janus form, which uses an AdS _p−1 slicing of AdS _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 AdS ₃× S ¹ D3-branes in the AdS ₅× S ⁵ solution of Type IIB, realizing interfaces on surface defects in N = 4 SYM, and show that similar solutions exist for probe branes in AdS _p+2× S ^9−p vacua of M-theory and in the AdS ₆× S ⁴ solution of massive Type IIA.
