Abstract We derive a compact formula for the one-loop, bosonic string partition function of Euclideanized J 3 J ¯ 3 $$ {J}_3{\overline{J}}_3 $$ deformed AdS 3 with periodic Euclidean time as an integral transform of the partition function of the und

Abstract In single-trace T T ¯ $$ T\overline{T} $$ holography, for the negative sign of the deformation, the geometries dual to high energy states consist of a singular UV wall that separates black strings in the IR from an asymptotically linear dil

Abstract Aspects of superstring theory on deformed BTZ black holes, formed near k NS5 branes by p fundamental strings, and single-trace T T ¯ $$ T\overline{T} $$ holography, are presented. The excitation energy of a singly wound long string plus its

Abstract The 2pf in single-trace T T ¯ $$ T\overline{T} $$ holography was computed and analyzed for operators in the w = 0 sector in [1]. Here we present its immediate generalization to non-zero winding w. For long strings, the result is identical t

We continue our exploration of the holographic duality between string theory in backgrounds that interpolate between asymptotically linear dilaton spacetime in the UV and AdS3 in the IR, and the corresponding boundary theories. In previous papers, [1

Aspects of shock waves and instantly-created folded strings operators in the supersymmetric SL(2)k/U(1) CFT, and their relevance to the near-horizon physics of Schwarzschild black holes in perturbative superstring theory, are presented.

Abstract We consider the backreaction of the winding condensate on the cigar background. We focus on the case of the SL(2, ℝ) k /U(1) cigar associated with, e.g., the near-horizon limit of k NS5 black-branes. We solve the equations of motion numeri

Abstract We propose a new AdS 3 /CFT 2 duality, in which the bulk string theory has a target spacetime AdS 3 times a squashed three-sphere S ♭ 3 $$ {\mathbbm{S}}_{\flat}^3 $$ , and the dual CFT 2 is a symmetric product of sigma models on ℝ ϕ ×

Abstract The claim that the microstates of Schwarzschild black holes in perturbative string theory amount to the modes of long folded strings in the vicinity of its horizon is supported by more evidence.
