Genus Two Surface and Quarter BPS Dyons: The Contour Prescription
Shamik Banerjee, Ashoke Sen, Yogesh K. Srivastava
Following the suggestion of hep-th/0506249 and hep-th/0612011, we represent quarter BPS dyons in N=4 supersymmetric string theories as string network configuration and explore the…
Partition Functions of Torsion >1 Dyons in Heterotic String Theory on T^6
Shamik Banerjee, Ashoke Sen, Yogesh K. Srivastava
The original proposal of Dijkgraaf, Verlinde and Verlinde for the quarter BPS dyon partition function in heterotic string theory on T^6 is known to correctly produce the degeneracy…
Generalities of Quarter BPS Dyon Partition Function and Dyons of Torsion Two
Shamik Banerjee, Ashoke Sen, Yogesh K. Srivastava
We propose a general set of constraints on the partition function of quarter BPS dyons in any N=4 supersymmetric string theory by drawing insight from known examples, and study the…
Bound states of KK monopole and momentum
Yogesh K. Srivastava
We construct metrics for multiple Kaluza-Klein monopole-branes carrying travelling waves along one of the isometry directions (not KK monopole fibre) in ten dimensional type IIB su…
Perturbations of supertube in KK monopole background
Yogesh K. Srivastava
We study perturbations of supertube in KK monopole background, at both DBI and supergravity levels. We analyse both NS1-P as well as D0-F1 duality frames and study different profil…
A microstate for the 3-charge black ring
Stefano Giusto, Samir D. Mathur, Yogesh K. Srivastava
We start with a 2-charge D1-D5 BPS geometry that has the shape of a ring; this geometry is regular everywhere. In the dual CFT there exists a perturbation that creates one unit of…
