Ultracold horizons in gauged N=1 d=4 supergravity

TL;DR

This paper demonstrates that the near-horizon geometry of ultracold magnetic Reissner-Nordstrom-De Sitter black holes in gauged N=1 d=4 supergravity preserves half of the supersymmetries, revealing supersymmetric properties of these extremal black holes.

Contribution

It shows that the near-horizon limit of ultracold magnetic Reissner-Nordstrom-De Sitter black holes preserves half of the supersymmetries in minimal R-gauged N=1 d=4 supergravity.

Findings

Near-horizon geometry is a product of 2D Minkowski space and a 2-sphere.

Supersymmetry is preserved in the near-horizon limit.

Half of the supersymmetries are preserved in the ultracold black hole horizon.

Abstract

We show that the near-horizon limit of ultracold magnetic Reissner-Nordstrom-De Sitter black holes, whose geometry is the direct product of 2-dimensional Minkowski spacetime and a 2-sphere, preserves half of the supersymmetries of minimal R-gauged N=1 d=4 supergravity.
