We construct general 2-charge D1-D5 horizon-free non-singular solutions of IIB supergravity on T4 and K3 describing fuzzballs with excitations in the internal manifold; these excitations are characterized by arbitrary curves. The solutions are obtained via dualities from F1-P solutions of heterotic and type IIB on T4 for the K3 and T4 cases, respectively. We compute the holographic data encoded in these solutions, and show that the internal excitations are captured by vevs of chiral primaries… 
Superdescendants of the D1D5 CFT and their dual 3-charge geometries
A bstractWe describe how to obtain the gravity duals of semiclassical states in the D1-D5 CFT that are superdescendants of a class of RR ground states. On the gravity side, the configurations we
Global structure of five-dimensional fuzzballs
We describe and study families of BPS microstate geometries, namely, smooth, horizonless asymptotically flat solutions to supergravity. We examine these solutions from the perspective of earlier
Adding new hair to the 3-charge black ring
Motivated by the string theory analysis of Giusto et al (2011 JHEP1111(2011)062), we construct a class of 1/8-BPS solutions of type-IIB supergravity compactified on S1 × T4. In this duality frame,
Three-charge superstrata with internal excitations
We construct a new family of three-charge -BPS smooth solutions that have the same charges as the supersymmetric D1D5P black hole and are non-invariant under rotations of the compact manifold. We
Supercharged AdS3 Holography
Abstract Given an asymptotically Anti-de Sitter supergravity solution, one can obtain a microscopic interpretation by identifying the corresponding state in the holographically dual conformal field
Multi-centered D1-D5 solutions at finite B-moduli
A bstractWe study the fate of two-centered D1-D5 systems on T4 away from the singular supergravity point in the moduli space. We do this by considering a background D1-D5 black hole with a self-dual
Effect of the deformation operator in the D1D5 CFT
A bstractThe D1D5 CFT gives a holographic dual description of a near-extremal black hole in string theory. The interaction in this theory is given by a marginal deformation operator, which is
5D fuzzball geometries and 4D polar states
We analyze the map between a class of `fuzzball' solutions in five dimensions and four-dimensional multicentered solutions under the 4D-5D connection, and interpret the resulting configurations in
String dynamics in NS5-F1-P geometries
A bstractString theory dynamics on certain fivebrane supertube backgrounds is described by an exactly solvable null-gauged WZW model. We use this description to compute the spectrum of closed string
Unitary 4-point correlators from classical geometries
In all cases, the correlators of two heavy and two light operators in the strong coupling and large c limit of the D1D5 CFT find that they have the properties expected for correlators among pure states in a unitary theory, in particular they do not decay at large Lorentzian times.


Holographic anatomy of fuzzballs
We present a comprehensive analysis of 2-charge fuzzball solutions, that is, horizon-free non-singular solutions of IIB supergravity characterized by a curve on R4. We propose a precise map that
Kaluza-Klein Holography
We construct a holographic map between asymptotically AdS5 × S5 solutions of 10d supergravity and vacuum expectation values of gauge invariant operators of the dual QFT. The ingredients that enter in
D1-D5 black hole microstate counting from supergravity
We quantize the moduli space of regular D1-D5 microstates, directly from Type IIB SUGRA. The moduli space is parametrized by a smooth closed non-selfintersecting curve in four dimensions, and we

We discuss a generalized form of IIA/IIB supergravity depending on all R-R potentials C-(p) (p = 0, 1,..., 9) as the effective field theory of type IIA/IIB superstring theory. For the IIA case we

The holographic Weyl anomaly
We calculate the Weyl anomaly for conformal field theories that can be described via the adS/CFT correspondence. This entails regularizing the gravitational part of the corresponding supergravity

Supersymmetric Conical Defects: Towards a string theoretic description of black hole formation
Conical defects, or point particles, in $AdS_3$ are one of the simplest non-trivial gravitating systems, and are particularly interesting because black holes can form from their collision. We embed
