Covering space maps for -point functions with three long twists
Benjamin A. Burrington, Ida G. Zadeh
We consider correlation functions in symmetric product orbifold CFTs on the sphere, focusing on the case where all operators are single-cycle twists, and the covering surface is al…
Conformal Perturbation Theory for -Point Functions: Structure Constant Deformation
Benjamin A. Burrington, Ida G. Zadeh
We consider conformal perturbation theory for -point functions on the sphere in general 2D CFTs to first order in coupling constant. We regulate perturbation integrals using can…
Heterotic Strings on , Nikulin involutions and M-theory

We first describe the low energy dynamics of ten dimensional heterotic supergravity compactified on the smooth, flat 3-manifold , without supersymmetry…
Lifting 1/4-BPS States in
Nathan Benjamin, Christoph A. Keller, Ida G. Zadeh
We establish a framework for doing second order conformal perturbation theory for the symmetric orbifold Sym to all orders in . This allows us to compute how 1/4-BPS st…
Narain to Narnia
Nathan Benjamin, Christoph A. Keller, Hirosi Ooguri +1
We generalize the holographic correspondence between topological gravity coupled to an abelian Chern-Simons theory in three dimensions and an ensemble average of Narain's family of…
On Rational Points in CFT Moduli Spaces
Nathan Benjamin, Christoph A. Keller, Hirosi Ooguri +1
Motivated by the search for rational points in moduli spaces of two-dimensional conformal field theories, we investigate how points with enhanced symmetry algebras are distributed…
Stringy Tachyonic Instabilities of Non-Supersymmetric Ricci Flat Backgrounds
Bobby Samir Acharya, Gerardo Aldazabal, Eduardo Andrés +3
Superstring/M-theory compactified on compact Ricci flat manifolds have recently been conjectured to exhibit instabilities whenever the metrics do not have special holonomy. We use…
Conformal Perturbation Theory for Twisted Fields
Christoph A. Keller, Ida G. Zadeh
We investigate second order conformal perturbation theory for orbifolds of conformal field theories in two dimensions. To evaluate the necessary twisted sector corre…
Lifting 1/4-BPS States on K3 and Mathieu Moonshine
Christoph A. Keller, Ida G. Zadeh
The elliptic genus of K3 is an index for the 1/4-BPS states of its sigma model. At the torus orbifold point there is an accidental degeneracy of such states. We blow up the orbifol…

Lorenz Eberhardt, Ida G. Zadeh
We consider string theory on AdS (S S S, a background supporting spacetime supersymmetry. We propose that…
Lifting of D1-D5-P states
Shaun Hampton, Samir D. Mathur, Ida G. Zadeh
We consider states of the D1-D5 CFT where only the left-moving sector is excited. As we deform away from the orbifold point, some of these states will remain BPS while others can `…
Bootstrapping Chiral CFTs at Genus Two
Christoph A. Keller, Gregoire Mathys, Ida G. Zadeh
Genus two partition functions of 2d chiral conformal field theories are given by Siegel modular forms. We compute their conformal blocks and use them to perform the conformal boots…
Genus Two Partition Functions and Renyi Entropies of Large c CFTs
Alexandre Belin, Christoph A. Keller, Ida G. Zadeh
We compute genus two partition functions in two dimensional conformal field theories at large central charge, focusing on surfaces that give the third Renyi entropy of two interval…

We consider the D1-D5 CFT near the orbifold point, specifically the computation of correlators involving twist sector fields using covering surface techniques. As is well known, ce…
Higgsing the stringy higher spin symmetry
Matthias R. Gaberdiel, Cheng Peng, Ida G. Zadeh
It has recently been argued that the symmetric orbifold theory of T4 is dual to string theory on AdS3 x S3 x T4 at the tensionless point. At this point in moduli space, the theory…
Renyi Entropies, the Analytic Bootstrap, and 3D Quantum Gravity at Higher Genus
Matthew Headrick, Alexander Maloney, Eric Perlmutter +1
We compute the contribution of the vacuum Virasoro representation to the genus-two partition function of an arbitrary CFT with central charge . This is the perturbative pure g…
Analyzing the squeezed state generated by a twist deformation
Benjamin A. Burrington, Samir D. Mathur, Amanda W. Peet +1
The D1D5 CFT has provided a useful microscopic model for studying black holes. The coupling in this theory is a twist deformation whose action on the vacuum generates a squeezed st…
The a-theorem for the four-dimensional gauged vector model
Howard J. Schnitzer, Ida G. Zadeh
The discussion of renormalization group flows in four-dimensional conformal field theories has recently focused on the a-anomaly. It has recently been shown that there is a monoton…
