Index saddle for the D1-D5-P black string and its decoupling limit
Kanhu Kishore Nanda, P Shanmugapriya, Amitabh Virmani
Boruch, Emparan, Iliesiu, and Murthy recently discussed index saddles for 5d black strings, showing that the black string saddle admits a decoupling limit to a complex, finite-temp…

Supersymmetric Index for Half BPS Black Holes in N=2 Supergravity with Higher Curvature Corrections
Subramanya Hegde, Ashoke Sen, P Shanmugapriya +1
We compute the supersymmetric index of half BPS black holes in N=2 supergravity with higher curvature corrections and show that the result agrees with the degeneracy of supersymmet…
