We describe holographic properties of near-AdS2 spacetimes that arise within spherically symmetric configurations of N = 2 4D U(1)4 supergravity, for both gauged and ungauged theories. These theories pose a rich space of AdS2 × S2 backgrounds, and their responses in the nearAdS2 region are not universal. In particular, we show that the spectrum of operators dual to the matter fields, and their cubic interactions, are sensitive to properties of the background and the theory it is embedded in…

Freudenthal duality of near-extremal black holes and JT gravity
Freudenthal duality (F-duality), an anti-involution of charge vectors keep the entropy and attractor solutions invariant for an extremal supersymmetric black hole. In this paper, we analyze the
