Semi-classical analysis of the string theory cigar
- MathematicsJournal of High Energy Physics
- 2021
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…

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…
Holographic approach to deformations of NS5-brane distributions and exact CFTs
- Physics
- 2007
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
- Physics
- 2005
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
- Physics
- 2008
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
- PhysicsPhysical Review D
- 2021
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
- Physics
- 2007
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
- Physics
- 2004
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…
Strings from Tachyons
- Physics
- 2003
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
- Physics
- 1997
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''…
Some remarks on D-branes in AdS
- Mathematics
- 2001
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
- Physics, Mathematics
- 1998
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
- Physics
- 2001
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…
