We find the most general supergravity solution in an $AdS^3 \times S^3$ background preserving an $AdS_2 \times S^2$ symmetry and half the supersymmetries. Contrary to previous expectations from boundary state arguments, it is shown that no solutions exist containing localized brane sources.

Exact half-BPS string-junction solutions in six-dimensional supergravity

A bstractWe construct SO(2, 1) × SO(3)-invariant half-BPS solutions in six-dimensional (0,4) supergravity with m tensor multiplets. The space-time manifold of each one of these solutions consists of

Anti-de Sitter D-branes in curved backgrounds

We investigate the properties of the AdS D1-branes which are the bound states of a curved D1-brane with n fundamental strings (F1) in the AdS3 spacetime, and the AdS D2-branes which are the axially

Boundary entropy of supersymmetric Janus solutions

In this paper we compute the holographic boundary entropy for half-BPS Janus deformations of the AdS3 × S3 × T4 vacuum of type IIB supergravity. Previous work [24] has shown that there are two

Open worldsheets for holographic interfaces

Type IIB supergravity admits Janus and multi-Janus solutions with eight unbroken supersymmetries that are locally asymptotic to AdS3 × S3 × M4 (where M4 is either T4 or K3). These solutions are dual

String junctions and holographic interfaces

In this paper we study half-BPS type IIB supergravity solutions with multiple ${\mathrm{AdS}}_{3}\ifmmode\times\else\texttimes\fi{}{S}^{3}\ifmmode\times\else\texttimes\fi{}{M}_{4}$ asymptotic
