On Quantum Special Kaehler Geometry
S. Bellucci, A. Marrani, R. Roychowdhury
We compute the effective black hole potential V of the most general N=2, d=4 (local) special Kaehler geometry with quantum perturbative corrections, consistent with axion-shift Pec…
Attractor Flows in st^2 Black Holes
Raju Roychowdhury
Following the same treatment of Bellucci et.al., we obtain the hitherto unknown general solutions of the radial attractor flow equations for extremal black holes, both for non-BPS…
On the complete analytic structure of the massive gravitino propagator in four-dimensional de Sitter space
Giampiero Esposito, Raju Roychowdhury
With the help of the general theory of the Heun equation, this paper completes previous work by the authors and other groups on the explicit representation of the massive gravitino…
Spinor two-point functions and Peierls bracket in de Sitter space
Giampiero Esposito, Raju Roychowdhury
This paper studies spinor two-point functions for spin-1/2 and spin-3/2 fields in maximally symmetric spaces such as de Sitter spacetime, by using intrinsic geometric objects. The…
