Generating Function of Single Centered Black Hole Index from the Igusa Cusp Form
Ajit Bhand, Ashoke Sen, Ranveer Kumar Singh
We introduce manifestly duality invariant generating function of the index of single centered black holes in the heterotic string theory compactified on a six dimensional torus. Th…
Argyres-Douglas Theories, Macdonald Indices and Arc Space of Zhu Algebra
George Andrews, Anindya Banerjee, Chinmaya Bhargava +2
In this paper, we relate the MacDonald index of a 4d SCFT with the Hilbert series of the arc space of the Zhu algebra of the corresponding Schur VOA. Using this, we…
Mock Modularity Of Twisted Index In CHL Models
Nabamita Banerjee, Vedant Bhutra, Ranveer Kumar Singh
We study the twisted partition function of quarter BPS states in CHL models and show that for a large class of single-centered black holes, the degeneracy of microstates is given b…
Topological Twisting of 4d Supersymmetric Field Theories
Gregory W. Moore, Vivek Saxena, Ranveer Kumar Singh
We discuss what topological data must be provided to define topologically twisted partition functions of four-dimensional supersymmetric field theories. The origina…
