S-matrices in the holomorphic modular bootstrap approach
Suresh Govindarajan, Aditya Jain, Akhila Sadanandan +1
We numerically determine the S-matrix by using connection formulae in the modular linear differential equation (MLDE) approach to the holomorphic modular bootstrap. We then determi…
Elliptic curves in game theory
Abhiram Kidambi, Elke Neuhaus, Irem Portakal
We investigate Spohn curves, the algebro-geometric models of totally mixed dependency equilibria for normal-form games. These curves arise as the intersection of two q…
Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry and Complex Multiplication
Abhiram Kidambi, Masaki Okada, Taizan Watari
These notes combine results from two papers by the present authors viz., Part I (arXiv:2205.10299) and Part II (arXiv:2212.13028) into one streamlined version for better readabilit…
Generalized Narain Theories Decoded: Discussions on Eisenstein series, Characteristics, Orbifolds, Discriminants and Ensembles in any Dimension
Meer Ashwinkumar, Abhiram Kidambi, Jacob M. Leedom +1
We study a class of newly-introduced CFTs associated with even quadratic forms of general signature, which we call generalized Narain theories. We first summarize the properties of…
Dyonic black hole degeneracies in string theory from Dabholkar-Harvey degeneracies
Abhishek Chowdhury, Abhiram Kidambi, Sameer Murthy +2
The degeneracies of single-centered dyonic -BPS black holes (BH) in Type II string theory on K3 are known to be coefficients of certain mock Jacobi forms arisi…
Heterotic strings on and their dual Calabi-Yau threefolds
Andreas Banlaki, Aradhita Chattopadhyaya, Abhiram Kidambi +2
In this paper we study compactifications of the heterotic string on with various gauge backgrounds and calculate the topo…
