Supersymmetry and Attractors in N = 4 Supergravity: The Superconformal Approach
Abhinava Bhattacharjee, Bindusar Sahoo
In this paper, we study the attractor mechanism for extremal, spherically symmetric black holes in pure, untruncated, N=4 Poincaré supergravity, which we demonstrate numerically.…

Only Flat Spacetime is Full BPS in Four Dimensional N=3 and N=4 Supergravity
Abhinava Bhattacharjee, Subramanya Hegde, Bindusar Sahoo
We investigate the fully supersymmetric solutions in a class of N=3 and N=4 higher derivative Poincaré supergravity theories. These class of theories are obtained within the frame…

BPS Solutions of 4d Euclidean N=2 Supergravity with Higher Derivative Interactions
Soumya Adhikari, Abhinava Bhattacharjee, Amitabh Virmani
We study fully BPS and a broad class of half-BPS stationary configurations of four-dimensional Euclidean N=2 supergravity with higher-derivative interactions. Working within the of…
