Abstract

We compute string amplitudes on pp-waves supported by NS-NS 3-form fluxes and arising in the Penrose limit of AdS3xS3xM. 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.

Aspects of the free field description of string theory on AdS 3
Carmen Núñez

Journal of High Energy Physics, 2000

The near boundary limit of string theory in AdS 3 is analysed using the Wakimoto free field representation of SL(2, R). The theory is considered as a direct product of the SL(2, R)/U(1) coset and a free boson. Correlation functions are constructed generalizing to the non-compact case the integral representation of conformal blocks introduced by Dotsenko in the compact SU(2) CFT. Sectors of the theory obtained by spectral flow manifestly appear. The formalism naturally leads to consider scattering processes violating winding number conservation. The consistency of the procedure is verified in the factorization limit.

Free field realization of superstring theory on AdS3
Carmen Nunez

Journal of High Energy Physics, 2004

The Coulomb gas representation of expectation values in SU (2) conformal field theory developed by Dotsenko is extended to the SL(2, R) WZW model and applied to bosonic string theory on AdS 3 and to Type II superstrings on AdS 3 × N. The spectral flow symmetry is included in the free field realization of vertex operators creating superstring states of both Ramond and Neveu-Schwarz sectors. Conjugate representations for these operators are constructed and a background charge prescription is designed to compute correlation functions. Two and three point functions of bosonic and fermionic string states in arbitrary winding sectors are calculated. Scattering amplitudes that violate winding number conservation are also discussed.

Asymptotic Symmetries of String Theory on AdS3 X S3 with Ramond-Ramond Fluxes
Jan Troost

HAL (Le Centre pour la Communication Scientifique Directe), 2009

String theory on AdS 3 space-times with boundary conditions that allow for black hole states has global asymptotic symmetries which include an infinite dimensional conformal algebra. Using the conformal current algebra for sigma-models on P SU (1, 1|2), we explicitly construct the R-symmetry and Virasoro charges in the worldsheet theory describing string theory on AdS 3 × S 3 with Ramond-Ramond fluxes. We also indicate how to construct the full boundary superconformal algebra. The boundary superconformal algebra plays an important role in classifying the full spectrum of string theory on AdS 3 with Ramond-Ramond fluxes, and in the microscopic entropy counting in D1-D5 systems.

Holographic reformulation of string theory on AdS5×S5 background in the PP-wave limit
T. Yoneya

Nuclear Physics B, 2003

The recent proposal on the correspondence between the N = 4 super Yang-Mills theory and string theory in the Penrose limit of the AdS 5 ×S 5 geometry involves a few puzzles from the viewpoint of holographic principle, especially in connection with the interpretation of times. To resolve these puzzles, we propose to interpret the PP-wave strings on the basis of tunneling null geodesics connecting boundaries of the AdS geometry. Our approach predicts a direct and systematic identification of the S-matrix of Euclidean string theory in the bulk with the short-distance structure of correlation functions of super Yang-Mills theory on the AdS boundary, as an extension of the ordinary relation in supergravity-CFT correspondence. Holography requires an infinite number of contact terms for interaction vertices of string field theory and constrains their forms in a way consistent with supersymmetry.

Superstrings on AdS3 at k = 1
E. Rabinovici

Journal of High Energy Physics, 2018

We study superstring theory in three dimensional Anti-de Sitter spacetime with NS-NS flux, focusing on the case where the radius of curvature is equal to the string length. This corresponds to the critical level k = 1 in the formulation as a Wess-Zumino-Witten model. Previously, it was argued that a transition takes place at this special radius, from a phase dominated by black holes at larger radius to one dominated by long strings at smaller radius. We argue that the infinite tower of modes that become massless at k = 1 is a signal of this transition. We propose a simple two-dimensional conformal field theory as the holographic dual to superstring theory at k = 1. As evidence for our conjecture, we demonstrate that our putative dual exactly reproduces the full spectrum of the long strings of the weakly coupled string theory, including states unprotected by supersymmetry.

Spectral flow and string correlators in AdS$_3\times S^3 \times T^4$
Julian Toro

arXiv (Cornell University), 2022

We consider three-point correlation functions for superstrings propagating in AdS 3 × S 3 × T 4. In the RNS formalism, these generically involve correlators with current insertions. When vertex operators with non-trivial spectral flow charges are present, their complicated OPEs with the currents imply that standard methods can not be used to compute such correlators. Here we develop techniques for computing all m-basis correlators of the supersymmetric model. We then show how, in some cases, these results can be translated to the x-basis. We obtain a new family of holographic three-point functions involving spacetime chiral primaries living in spectrally flowed sectors of the worldsheet CFT. These match precisely the predictions from the holographic dual at the symmetric product orbifold point. Finally, we also consider long strings and compute the probability amplitude associated with the process describing the emission/absorption of fundamental string quanta.

String theory on AdS3 × M7 in the tensionless limit
Gaston Giribet

International Journal of Modern Physics D, 2020

We review old and recent results on a special limit of string theory on [Formula: see text] with pure NS–NS fluxes: the limit in which the string length [Formula: see text] equals the [Formula: see text] radius [Formula: see text]. At this point of the moduli space, the theory exhibits special properties, which we discuss. Special attention is focused on features of correlation functions that are related to the noncompactness of the boundary CFT target space, and on how these features change when the point [Formula: see text] is approached. Also, we briefly review the recent proposals for exact realizations of AdS/CFT correspondence at this special point.

String correlators in AdS$_3$ from FZZ duality
Gaston Giribet

2021

Motivated by recent works in which the FZZ duality plays an important role, we revisit the computation of correlation functions in the sine-Liouville field theory. We present a direct computation of the three-point function, the simplest to the best of our knowledge, and give expressions for the N -point functions in terms of integrated Liouville theory correlators. This leads us to discuss the relation to the H 3 WZW-Liouville correspondence, especially in the case in which spectral flow is taken into account. We explain how these results can be used to study scattering amplitudes of winding string states in AdS3. ar X iv :2 11 0. 04 19 7v 2 [ he pth ] 1 3 O ct 2 02 1

Spacetime supersymmetry in AdS3 backgrounds

We construct string target spacetimes with AdS 3 × X geometry, which have an N = 2 spacetime superconformal algebra. X is found to be a U (1) fibration over a manifold which is a target for an N = 2 worldsheet conformal field theory. We emphasize theories with free field realizations where in principle it is possible to compute the full one-particle string spectrum. *

String theory on AdS 3
Jan De Boer

Journal of High Energy Physics, 1998

It was shown by Brown and Henneaux that the classical theory of gravity on AdS 3 has an infinite-dimensional symmetry group forming a Virasoro algebra. More recently, Giveon, Kutasov and Seiberg (GKS) constructed the corresponding Virasoro generators in the first-quantized string theory on AdS 3 . In this paper, we explore various aspects of string theory on AdS 3 and study the relation between these two works. We show how semi-classical properties of the string theory reproduce many features of the AdS/CFT duality. Furthermore, we examine how the Virasoro symmetry of Brown and Henneaux is realized in string theory, and show how it leads to the Virasoro Ward identities of the boundary CFT. The Virasoro generators of GKS emerge naturally in this analysis. Our work clarifies several aspects of the GKS construction: why the Brown-Henneaux Virasoro algebra can be realized on the first-quantized Hilbert space, to what extent the free-field approximation is valid, and why the Virasoro generators act on the string worldsheet localized near the boundary of AdS 3 . On the other hand, we find that the way the central charge of the Virasoro algebra is generated is different from the mechanism proposed by GKS.

The string theory on AdS3 as a marginal deformation of a linear dilaton background,” Nucl
Gaston Giribet

2013

We investigate N-point string scattering amplitudes in AdS3 space. Based on recent observations on the solutions of KZ and BPZ-type differential equations, we discuss how to describe the string theory in AdS3 as a marginal deformation of a (flat) linear dilaton background. This representation resembles the called “discrete light-cone Liouville ” realization as well as the FZZ dual description in terms of the sine-Liouville field theory. Consequently, the connection and differences between those and this realization are discussed. The free field representation presented here permits to understand the relation between correlators in both Liouville and WZNW theories in a very simple way. Within In this paper we study a representation of the N-point correlation functions describing string scattering amplitudes in Euclidean AdS3. The tree-level amplitudes of strings in this space were extensively studied in the literature and received renewed attention since the formulation of the AdS/CF...

Note on classical string dynamics on AdS3
Máximo Bañados

Physical Review D, 1999

We consider bosonic strings propagating on Euclidean adS 3 , and study in particular the realization of various worldsheet symmetries. We give a proper definition for the Brown-Henneaux asymptotic target space symmetry, when acting on the string action, and derive the Giveon-Kutasov-Seiberg worldsheet contour integral representation simply by using Noether's theorem. We show that making identifications in the target space is equivalent to the insertion of an (exponentiated) graviton vertex operator carrying the corresponding charge. Finally, we point out an interesting relation between 3D gravity and the dynamics of the worldsheet on adS 3 . Both theories are described by an SL(2,C)/SU (2) WZW model, and we prove that the reduction conditions determined on one hand by worldsheet diffeomorphism invariance, and on the other by the Brown-Henneaux boundary conditions, are the same.

    Closed strings in Misner space: stringy fuzziness with a twist
    Dori Reichmann

    Journal of Cosmology and Astroparticle Physics, 2004

    Misner space, also known as the Lorentzian orbifold $R^{1,1}/boost$, is the simplest tree-level solution of string theory with a cosmological singularity. We compute tree-level scattering amplitudes involving twisted states, using operator and current algebra techniques. We find that, due to zero-point quantum fluctuations of the excited modes, twisted strings with a large winding number $w$ are fuzzy on a scale $\sqrt{\log w}$, which can be much larger than the string scale. Wave functions are smeared by an operator $\exp(\Delta(\nu) \partial_+ \partial_-)$ reminiscent of the Moyal-product of non-commutative geometry, which, since $\Delta(\nu)$ is real, modulates the amplitude rather than the phase of the wave function, and is purely gravitational in its origin. We compute the scattering amplitude of two twisted states and one tachyon or graviton, and find a finite result. The scattering amplitude of two twisted and two untwisted states is found to diverge, due to the propagation of intermediate winding strings with vanishing boost momentum. The scattering amplitude of three twisted fields is computed by analytic continuation from three-point amplitudes of states with non-zero $p^+$ in the Nappi-Witten plane wave, and the non-locality of the three-point vertex is found to diverge for certain kinematical configurations. Our results for the three-point amplitudes allow in principle to compute, to leading order, the back-reaction on the metric due to a condensation of coherent winding strings.

    AdS/CFT v.s. string loops
    Marta Orselli

    Journal of High Energy Physics, 2006

    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 Yoneya. As in previous published computations, the string vertices are truncated to the 2-impurity channel. The result is compared with the prediction from non-planar corrections in the BMN limit of N = 4 supersymmetric Yang-Mills theory. It is found to agree at leading order -one-loop in Yang-Mills theory -and is close but not quite in agreement at order two Yang-Mills loops. Furthermore, in addition to the leading 1/2 power in the t'Hooft coupling, which is generic in string field theory, and which we have previously argued cancels, we find that the 3/2 and 5/2 powers are also miraculously absent.

    Cubic interactions in the Berenstein-Maldacena-Nastase limit of AdS3×S3

    Physical Review D, 2004

    We study the pp limit of AdS 3 × S 3 at the interaction level. We find the interacting Hamiltonian for the bosonic fields of D = 6 SUGRA in the pp-wave background, and compare it to the cubic couplings of the full AdS 3 × S 3 . We show how the pp-wave theory vertex arises in the large J limit. Our analysis also provides some insight into the origin of specific "prefactors" which appear in the pp-wave interaction.
