    Ensemble averages of 2 orbifold classes of Narain CFTs

    In this work we study families of 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...

    Deformations 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...

    Quantum 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...

    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...

    Perturbative Corrections to Kähler Moduli Spaces
