Two Centered Black Holes and N=4 Dyon Spectrum
نویسنده
چکیده
The exact spectrum of dyons in a class of N=4 supersymmetric string theories is known to change discontinuously across walls of marginal stability. We show that the change in the degeneracy across the walls of marginal stability can be accounted for precisely by the entropy of two centered small black holes which (dis)appear as we cross the walls of marginal stability.

P-brane Black Holes for General Intersections
Black hole generalized p -brane solutions for a wide class of intersection rules are presented. The solutions are defined on a manifold that contains a product of n−1 Ricci-flat internal spaces. They are defined up to moduli functions Hs = Hs(R) obeying a non-linear differential equations (equivalent to Toda-type equations) with certain boundary conditions imposed. Using conjecture on polynomia...
متن کاملGravitating Dyons and Dyonic Black Holes
We study static spherically symmetric gravitating dyon solutions and dyonic black holes in Einstein-Yang-Mills-Higgs theory. The gravitating dyon solutions share many features with the gravitating monopole solutions. In particular, gravitating dyon solutions and dyonic black holes exist only up to a maximal coupling constant, and beside the fundamental dyon solutions there are excited dyon solu...
متن کاملA Farey tale for N = 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 AdS3 region, we identify an infinite family of semi-classical AdS2 geometries which can contribute effects of order exp(S0/c), where S0 is the Bekenstein-Hawking-Wald entropy and c is an integer gre...
متن کاملWalls of Marginal Stability and Dyon Spectrum in N = 4 Supersymmetric String Theories
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 arg...
