Dyonic black hole degeneracies in $N = 4$ string theory from Dabholkar-Harvey degeneracies

Abhishek Chowdhury, Abhiram Kidambi, Sameer Murthy +2

The degeneracies of single-centered dyonic $\frac{1}{4}$ -BPS black holes (BH) in Type II string theory on K3 $\times T^{2}$ are known to be coefficients of certain mock Jacobi forms arisi…

One-loop determinants for black holes in 4d gauged supergravity

Kiril Hristov, Ivano Lodato, Valentin Reys

We continue the effort of defining and evaluating the quantum entropy function for supersymmetric black holes in 4d $N = 2$ gauged supergravity, initiated in [1803.05920]. T…
