Classical integrability and quantum aspects of the AdS 3 × S 3 × S 3 × S 1 superstring

The holographic dual of AdS 3 × S 3 × S 3 × S 1

We construct the two dimensional N = (0, 4) gauge theory that lives on the world volume of D1-branes and intersecting D5-branes. We conjecture that this theory flows in the infra-red to a fixed point with large N = (4, 4) superconformal symmetry. The central charge of the conformal field theory is shown to coincide with the holographic dual of string theory compactified on AdS3 × S × S × S.

AdS 3 × w ( S 3 × S 3 × S 1 ) Solutions of Type IIB String Theory

We analyse a recently constructed class of local solutions of type IIB supergravity that consist of a warped product of AdS3 with a sevendimensional internal space. In one duality frame the only other nonvanishing fields are the NS three-form and the dilaton. We analyse in detail how these local solutions can be extended to globally well-defined solutions of type IIB string theory, with the int...

Search for a holographic dual to AdS 3 × S 3 × S 3 × S 1

The problem of finding a holographic dual to string theory on AdS3 × S × S3 × S1 is examined in depth. This background supports a large N = 4 superconformal symmetry. While in some respects similar to the familiar small N = 4 systems on AdS3 × S3 ×K3 and AdS3 × S3 × T 4, there are important qualitative differences. Using an analogue of the elliptic genus for large N = 4 theories we rule out all...

D 1 and D 5 - brane giant gravitons on AdS 3 × S 3 × S 3 × S 1

We construct various examples of 14 -BPS giant gravitons embedded into the type IIB supergravity background AdS3×S +×S −×S with pure R-R flux: two D1-brane giants wrapping 1-cycles in AdS3 and S 3 +×S −, and one D5-brane giant wrapping a 4-cycle in S3 + × S3 − and the S1. These D-branes are supported by angular momenta αP on one 3-sphere and (1−α)P on the other. We then construct a general clas...
