A note on background independence in string theory
Bob Knighton
In this note, we comment on the path integral formulation of string theory on where is any hyperbolic 3-manifold. In t…
D-branes in at and their holographic duals
Matthias R. Gaberdiel, Bob Knighton, Jakub Vošmera
String theory on with minimal NS-NS flux can be described in terms of a free field worldsheet theory in the hybrid formalis…
Higher genus correlators for tensionless strings
Bob Knighton
It was recently shown in arXiv:2009.11306 that tree-level correlation functions in tensionless string theory on match the expected form…
From Symmetric Product CFTs to
Matthias R. Gaberdiel, Rajesh Gopakumar, Bob Knighton +1
Correlators in symmetric orbifold CFTs are given by a finite sum of admissible branched covers of the 2d spacetime. We consider a Gross-Mende like limit where all operators have la…
Free field world-sheet correlators for
Andrea Dei, Matthias R. Gaberdiel, Rajesh Gopakumar +1
We employ the free field realisation of the world-sheet theory to constrain the correlators of string theory on ${\rm AdS}_3\times {\rm S}^3\times \mathbb…
