The fuzzball proposal states that associated with a black hole of entropy S, there are
expShorizon-free non-singular solutions that asymptotically look like the black hole but …

A bstract Superstring theory on\({\mathrm {AdS}} _3\times {S}^ 3\times {\mathbb {T}}^ 4\) with
the smallest amount of NS-NS flux (“k= 1”) is shown to be dual to the spacetime CFT given …

Near-extremal black holes are obtained by exciting the Ramond sector of the D1-D5 CFT,
where the ground state is highly degenerate. We find that the dual geometries for these …

We construct a conformal field theory dual to string theory on AdS 3 with pure NS–NS flux. It
is given by a symmetric orbifold of a linear dilaton theory deformed by a marginal operator …

The black-hole information paradox provides one of the sharpest foci for the conflict between
quantum mechanics and general relativity and has become the proving-ground of would-be …

We develop a method for computing correlation functions of twist operators in the bosonic 2-
d CFT arising from orbifolds MN/SN, where M is an arbitrary manifold. The path integral with …

A bstract We continue our study of the worldsheet theory of superstrings on AdS 3× S 3× 𝕋 4
in the tensionless limit [1]. We consider the theory on higher genus surfaces. We give …

We investigate the AdS 3/CFT 2 correspondence for theories with 16 supercharges using
the integrability approach. We construct Green-Schwarz actions for Type IIB strings on AdS …

We construct general 2-charge D1-D5 horizon-free non-singular solutions of IIB supergravity
on T 4 and K3 describing fuzzballs with excitations in the internal manifold; these excitations …

A bstract Constructing a holographic string theory dual for a CFT in the perturbative, weakly
coupled regime is a holy grail for gauge/string dualities that would not only open the door for …
