Perturbative Corrections to Kähler Moduli Spaces
We propose a general formula for perturbative-in-α′ corrections to the Kähler potential on the quantum Kähler moduli space of Calabi–Yau n-folds, for any n, in their asymptotic large volume regime. The knowledge ...

Nonabelian 2D gauge theories for determinantal Calabi-Yau varieties
The two-dimensional supersymmetric gauged linear sigma model (GLSM) with abelian gauge groups and matter fields has provided many insights into string theory on Calabi-Yau manifolds of a certain type: complete...

SUSY enhancements in (0, 4) deformations of AdS3/CFT2
We discuss a marginal deformation of the SL(2, R) × SU(2) × U(1)4 WZW model, which describes string theory on AdS3 × S3 × T 4, that corresponds to war** the S3 factor. This deformation breaks part of the ...

\( \mathcal{N} = {1} \) sigma models in AdS4
We study sigma models in AdS4 with global \( \mathcal{N} = {1} \) supersymmetry and find that they differ significantly...

Open AccessComputing the spectrum of a heterotic flux vacuum
We compute the massless spectra of a set of flux vacua of the heterotic string. The vacua we study include well-known non-Kähler T 2-fibrations over K3 with SU(3) structure and intrinsic t...

Open AccessString theory on warped AdS3 and Virasoro resonances
We investigate aspects of holographic duals to time-like warped AdS 3 space-times — which include Gödel’s universe — in string theory. Using worldsheet techniques similar to those that hav...
