Abstract It is well-known that families of two-dimensional toroidal conformal field theories possess a dense subset of rational toroidal conformal field theories, which makes such families an interesting testing ground about rationality of conformal

Abstract We consider conformal perturbation theory for n-point functions on the sphere in general 2D CFTs to first order in coupling constant. We regulate perturbation integrals using canonical hard disk excisions of size ϵ around the fixed operator

Abstract In this work we study families of ℤ 2 orbifolds of toroidal conformal field theories based on both factorizable and non-factorizable target space tori. For these classes of theories, we analyze their moduli spaces, and compute their partit

Abstract We first describe the low energy dynamics of ten dimensional heterotic supergravity compactified on the smooth, flat 3-manifold T $$ \mathbbm{T} $$ 3/ℤ2, without supersymmetry, and explain how it arises from flat heterotic gauge fields. Th

Abstract We establish a framework for doing second order conformal perturbation theory for the symmetric orbifold Sym N (T 4) to all orders in N. This allows us to compute how 1/4-BPS states of the D1-D5 system on AdS 3 × S 3 × T 4 are lifted as we

Abstract 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 worldsheet conformal field theory to investigate instabilitie

Abstract 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 there. We first study the bosonic sigma-model with S 1 target

Abstract 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 ‘lift’. We compute this lifting for a particular family of

Abstract We consider string theory on AdS3 × (S3 × S3 × S1)/ℤ2, a background supporting N=33 $$ \mathcal{N}=\left(3,3\right) $$ spacetime supersymmetry. We propose that string theory on this background is dual to the symmetric product orbifold o

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 massless free bosons in two dimensions, discovered by Afkhami-Jeddi e
