Semi-classical analysis of the string theory cigar
Abstract We study the semi-classical limit of the reflection coefficient for the SL(2, ℝ)k/U(1) CFT. For large k, the CFT describes a string in a Euclidean black hole of 2-dimensional
Holography Beyond AdS
Stringy black hole interiors
Abstract It is well known that non-perturbative α ′ corrections to the SL(2, ℝ)/U(1) cigar geometry are described via a condensation of a Sine-Liouville operator that schematically can be
Wilson loop in a TT‾ like deformed CFT2
Holographic approach to deformations of NS5-brane distributions and exact CFTs
We consider general planar deformations of a circular distribution of NS5-branes. The near-horizon region of the latter admits, after a T-duality transformation, an exact conformal-field-theory
The Stoyanovsky-Ribault-Teschner Map and String Scattering Amplitudes
Recently, Ribault and Teschner pointed out the existence of a one-to-one correspondence between N-point correlation functions for the SL(2,C)_k/SU(2) WZNW model on the sphere and certain set of
Supersymmetric moduli of the SU(2) × ℝϕ linear dilaton background and NS5-branes
We study several classes of marginal deformations of the conformal field theory SU(2)k × R�. This theory describes the near-horizon region of a stack of parallel and coin- cident NS5-branes and is
Critical non-Abelian vortices and holography for little string theory
It has been shown that non-Abelian vortex string supported in four dimensional (4D) N = 2 supersymmetric QCD (SQCD) with the U(2) gauge group and Nf = 4 quark flavors becomes a critical superstring.
Large N gauge theories and topological cigars
We analyze the conjectured duality between a class of double-scaling limits of a one-matrix model and the topological twist of non-critical superstring backgrounds that contain the N = 2


A toy model for the AdS/CFT correspondence
We study the large-N gauged quantum mecchanics for a single hermitean matrix in the Harmonic oscillator potential well as a toy model for the AdS/CFT correspondence. We argue that the dual geometry
String Propagation in a Black Hole Geometry
Little string theory and heterotic/type II duality
Strings from Tachyons
We propose a new interpretation of the c=1 matrix model as the world-line theory of N unstable D-particles, in which the hermitian matrix is provided by the non- abelian open string tachyon. For
Proposals on nonperturbative superstring interactions
We show a possibility that the matrix models recently proposed to explain (almost) all the physics of M-theory may include the superstring theories that we know perturbatively. The ``1st quantized''
Notes on $AdS_3$
Some remarks on D-branes in AdS
We investigate the relation between the algebraic construction of boundary states in AdS3 and the target space analysis of D-branes and show the consistency of the two descriptions. We compute, in
Linear dilatons, NS5-branes and holography
We argue that vacua of string theory which asymptote at weak coupling to linear dilaton backgrounds are holographic. The full string theory in such vacua is ``dual'' to a theory without gravity in
Correlators in AdS_3 string theory
The computation of two and three point functions in the Coulomb gas free field approach to string theory in the SL(2,R)/U(1) black hole background is reviewed. An interesting relation arises when
D-brane Decay in Two-Dimensional String Theory
We consider unstable D0-branes of two dimensional string theory, described by the boundary state of Zamolodchikov and Zamolodchikov [hep-th/0101152] multiplied by the Neumann boundary state for the
