Open AccessEnsemble averages of ℤ2 orbifold classes of Narain CFTs
In this work we study families of ℤ2 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...

Open AccessDeformations of JT gravity via topological gravity and applications
We study the duality between JT gravity and the double-scaled matrix model including their respective deformations. For these deformed theories we relate the thermal partition function to the generating functi...

Open AccessQuantum K-theory of Calabi-Yau manifolds
The disk partition function of certain 3d N = 2 supersymmetric gauge theories computes a quantum K-theoretic ring for Kähler manifolds X. We study the 3d gauge theory/quantum K-theory correspondence for global an...

SU(N) Transitions in M-Theory on Calabi–Yau Fourfolds and Background Fluxes
We study M-theory on a Calabi–Yau fourfold with a smooth surface S of A N–1 singularities. The resulting three-dimensional theory has a

A Note on Colored HOMFLY Polynomials for Hyperbolic Knots from WZW Models
Using the correspondence between Chern-Simons theories and Wess-Zumino-Witten models, we present the necessary tools to calculate colored HOMFLY polynomials for hyperbolic knots. For two-bridge hyperbolic knot...

Knot Invariants from Topological Recursion on Augmentation Varieties
Using the duality between Wilson loop expectation values of SU(N) Chern–Simons theory on S 3 and topological open-string amplitudes on the local mirror of the resolved conifold, we study knots on

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 ...

Torus Knots and the Topological Vertex
We propose a class of toric Lagrangian A-branes on the resolved conifold that is suitable to describe torus knots on S 3. The key role is played by the

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...

Flat connections in open string mirror symmetry
We study a flat connection defined on the open-closed deformation space of open string mirror symmetry for type II compactifications on Calabi-Yau threefolds with D-branes. We use flatness and integrability co...

Type II/F-theory superpotentials with several deformations and \( \mathcal{N} = 1 \) mirror symmetry
We present a detailed study of D-brane superpotentials depending on several open and closed-string deformations. The relative cohomology group associated with the brane defines a generalized hypergeometric GKZ...

Effective Superpotentials for Compact D5-Brane Calabi-Yau Geometries
For compact Calabi-Yau geometries with D5-branes we study N = 1 effective superpotentials depending on both open- and closed-string fields. We develop methods to derive the open/closed Picard-Fuchs differential e...
