Janus on the brane

Abstract

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 AdSp × S1 embedded in an AdSp+2 × ℳD − p − 2 background to an embedding of Janus form, which uses an AdSp−1 slicing of AdSp 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 AdS3 × S1 D3-branes in the AdS5 × S5 solution of Type IIB, realizing interfaces on surface defects in

N

$$ \mathcal{N} $$ = 4 SYM, and show that similar solutions exist for probe branes in AdSp+2 × S9−p vacua of M-theory and in the AdS6 × S4 solution of massive Type IIA.
