Duality Symmetry and the Cardy Limit
Suresh Nampuri, Prasanta K. Tripathy, Sandip P. Trivedi
We study supersymmetric and non-supersymmetric extremal black holes obtained in Type IIA string theory compactified on K3 X T^2, with duality group O(6,22,Z) X SL(2,Z). In the Card…
On The Stability of Non-Supersymmetric Attractors in String Theory
Suresh Nampuri, Prasanta K. Tripathy, Sandip P. Trivedi
We study non-supersymmetric attractors obtained in Type IIA compactifications on Calabi Yau manifolds. Determining if an attractor is stable or unstable requires an algebraically c…
Comments on the Spectrum of CHL Dyons
Atish Dabholkar, Davide Gaiotto, Suresh Nampuri
We address a number of puzzles relating to the proposed formulae for the degeneracies of dyons in orbifold compactifications of the heterotic string to four dimensions with …
