We compute string amplitudes on pp-waves supported by NS-NS 3-form fluxes and arising in the Penrose limit of AdS3 × S3 × . We clarify the role of the non-chiral accidental SU(2) symmetry of the background. We comment on the extension of our results to the superstring and propose a holographic formula in the BMN limit of the AdS3/CFT2 correspondence valid for any correlator. 

On Hpp wave / CFT(2) holography

We briefly review the AdS3/CFT2 correspondence and the holographic issues that arise in the Penrose limit. Exploiting current algebra techniques, developped by D'Appollonio and Kiritsis for the

AdS/CFT v.s. string loops

The one string-loop correction to the energies of two impurity BMN states are computed using IIB light-cone string field theory with an improved 3-string vertex that has been proposed by Dobashi and

The diagonal cosets of the Heisenberg group

In this paper we study the diagonal cosets of the non-compact H4 WZW model. Generalising earlier work by Antoniadis and Obers, we provide an exact world-sheet description for several families of

Large-N limits of 2d CFTs, quivers and AdS3 duals

We explore the large-N limits of 2d CFTs, focusing mostly on WZW models and their cosets. The SU(N)k theory is parametrized in this limit by a ’t Hooft-like coupling. We show a duality between strong

Interactions for winding strings in Misner space

We compute correlation functions of closed strings in Misner space, which is a big crunch/big bang universe. We develop a general method for correlators with twist fields, which are relevant for the

The abelian cosets of the Heisenberg group

In this paper we study the abelian cosets of the H4 WZW model. They coincide or are related to several interesting three-dimensional backgrounds such as the Melvin model, the conical point-particle

Winding string condensation and noncommutative deformation of a spacelike singularity

In a previous paper [Jian-Huang She, J. High Energy Phys. 01 (2006) 002.] using a matrix model, we showed that closed string tachyons can resolve spacelike singularity in one particular class of

BOUNDARY STATES IN THE NAPPI–WITTEN MODEL

We investigate D-branes in the Nappi–Witten model. Classically symmetric D-branes are classified by the (twisted) conjugacy classes of the Nappi–Witten group, which specify the geometry of the

In this paper we study the diagonal cosets of the non-compact H4 WZW model. Generalising earlier work by Antoniadis and Obers, we provide an exact worldsheet description for several families of

We test the spectrum of string theory on AdS5 ? S5 derived in [1] against that of single-trace gauge invariant operators in free = 4 super Yang-Mills theory. Masses of string excitations at critical

We clarify a number of issues regarding the worldsheet and spacetime descriptions of string propagation on AdS3. We construct the vertex operators of spacetime current algebra and spacetime (super)

Comments on string theory on AdS(3)

We study string propagation on $AdS_3$ times a compact space from an ``old fashioned'' worldsheet point of view of perturbative string theory. We derive the spacetime CFT and its Virasoro and current

We investigate the pp-wave limit of the AdS3 × S ×K3 compactification of Type IIB string theory from the point of view of the dual SymN(K3) CFT. It is proposed that a fundamental string in this

Superstrings on AdS_3 and Symmetric Products

Some properties of N=2 superstrings on AdS_3 x N are studied. Their spectrum has the same pattern as 2-d CFTs in the moduli space of symmetric products M^p/S_p, where p is associated with the number

We consider correlation functions for string theory on AdS3. We analyze their singularities and we provide a physical interpretation for them. We explain which worldsheet correlation functions have a

We investigate the correspondence between superstring theory on pp-wave background with NSNS-flux and superconformal field theory on a symmetric orbifold. This correspondence can be regarded as the

Strings in flat space and pp waves from N = 4 Super Yang Mills
