Abstract
We consider different (supersymmetric) brane intersections in type IIB string theory that preserve (1 + 1)D Lorentz symmetry. We provide the full supergravity solutions in their analytic form and discuss their physical properties. The Ansatz for the spacetime dependence of the different brane warp factors goes beyond the harmonic superposition principle. By studying the associated near-horizon geometry, we construct interesting classes of AdS3 vacua in type IIB and highlight their relation to the existing classifications in the literature. Finally, we discuss their holographic properties.
Highlights
A crucially different physical situation of this type is that of having an asymptotically AdS curved domain wall (DW). Such geometries were proposed in [6,7,8] to provide a holographic description of defect CFTs. This was originally illustrated in the context of Janus solutions describing a conformal interface within N = 4 SYM engineered by means of a position-dependent profile for the gauge coupling
We explore a set of brane intersections (i) containing at least one D3 brane, (ii) with no isometry directions along the orthogonal directions of the D3 brane and (iii) admitting AdS3 vacua
We shall rely on the technique developed in [32] for constructing supergravity solutions describing semilocalized brane intersections, i.e. where the different brane charge distributions no longer obey the harmonic superposition principle
Summary
As explained in appendix B, such a brane intersection turns out to preserve four real supercharges, i.e. Even though no lower-dimensional CFT is expected to emerge in the (new) near-horizon limit, we look for the supergravity description of the field theory construction illustrated in [21]. Even though no lower-dimensional CFT is expected to emerge in the (new) near-horizon limit, we look for the supergravity description of the field theory construction illustrated in [21] To this end, the 10D supergravity Ansatz we cast is. The class of solutions presented here does not contain any obvious AdS3 solutions to be obtained by means of an appropriate near-horizon procedure They have a possible interesting physical interpretation as the gravity duals of the position dependent configurations of the coupling within N = 4 SYM, which were studied in [22].
