The spectrum of quarter BPS dyons in N = 4 supersymmetric string theories can change as the asymptotic moduli cross walls of marginal stability on which the dyon can break apart into a pair of half BPS states. In this paper we classify these marginal stability walls and examine this phenomenon in the context of exact dyon spectrum found in a class of N = 4 supersymmetric string theories. We argue that the dyon partition functions in different domains separated by marginal stability walls are…

On walls of marginal stability in N=2 string theories

We study the properties of walls of marginal stability for BPS decays in a class of N = 2 theories. These theories arise in N = 2 string compactifications obtained as freely acting orbifolds of N = 4

Wall Crossing, Discrete Attractor Flow

The appearance of a generalized (or Borcherds-) Kac-Moody algebra in the spectrum of BPS dyons in N = 4, d = 4 string theory is elucidated. From the low-energy supergravity analysis, we identify its

Subleading and non-holomorphic corrections to N=2 BPS black hole entropy

BPS black hole degeneracies can be expressed in terms of an inverse Laplace transform of a partition function based on a mixed electric/magnetic ensemble, which involves a non-trivial integration

On the internal structure of dyons in N=4 super Yang-Mills theories

We use the low energy effective $U(1{)}^{r}$ action on the Coulomb branch of $\mathcal{N}=4$ super Yang-Mills theory to construct approximate field configurations for solitonic dyons in these

The gravitational path integral for $ N=4$ BPS black holes from black hole microstate counting

We use the exact degeneracy formula of single-centred 14 BPS dyonic black holes with unit torsion in 4D N = 4 toroidally compactified heterotic string theory to improve on the existing formulation of

Dying dyons don't count

The dyonic 1/4-BPS states in 4D string theory with = 4 spacetime supersymmetry are counted by a Siegel modular form. The pole structure of the modular form leads to a contour dependence in the

Counting all dyons in $ \mathcal{N} = 4 $ string theory

For dyons in heterotic string theory compactified on a six-torus, with electric charge vector Q and magnetic charge vector P, the positive integer I ≡ gcd(Q ∧ P) is an invariant of the U-duality

Do all BPS black hole microstates carry zero angular momentum?

A bstractFrom the analysis of the near horizon geometry and supersymmetry algebra it has been argued that all the microstates of single centered BPS black holes with four unbroken supersymmetries

No more walls! A tale of modularity, symmetry, and wall crossing for 1/4 BPS dyons

A bstractWe determine the generating functions of 1/4 BPS dyons in a class of 4d N$$ \mathcal{N} $$ = 4 string vacua arising as CHL orbifolds of K3 × T2, a classification of which has been recently

A Farey tale for = 4 dyons

We study exponentially suppressed contributions to the degeneracies of extremal black holes. Within Sen's quantum entropy function framework and focusing on extremal black holes with an intermediate



Asymptotic degeneracy of dyonic N=4 string states and black hole entropy

It is shown that the asymptotic growth of the microscopic degeneracy of BPS dyons in four-dimensional N = 4 string theory captures the known corrections to the macroscopic entropy of four-dimensional

Dyon Spectrum in N=4 Supersymmetric Type II String Theories

We compute the spectrum of quarter BPS dyons in freely acting Z 2 and Z 3 orbifolds of type II string theory compactified on a six dimensional torus. For large charges the result for statistical

Split attractor flows and the spectrum of BPS D-branes on the quintic

We investigate the spectrum of type-IIA BPS D-branes on the quintic from a four-dimensional supergravity perspective and the associated split attractor flow picture. We obtain some very concrete

Dyon Spectrum in Generic N=4 Supersymmetric Z_N Orbifolds

We find the exact spectrum of a class of quarter BPS dyons in a generic N=4 supersymmetric Z_N orbifold of type IIA string theory on K3\times T^2 or T^6. We also find the asymptotic expansion of the

We present several pieces of evidence for strong–weak coupling duality symmetry in the heterotic string theory, compactified on a six-dimensional torus. They include symmetry of the (1) low energy

Entropy function for heterotic black holes

We use the entropy function formalism to study the effect of the Gauss-Bonnet term on the entropy of spherically symmetric extremal black holes in heterotic string theory in four dimensions.

Within effective heterotic superstring theory compactified on a six-torus we derive minimum energy (supersymmetric), static, spherically symmetric solutions, which are manifestly invariant under the
