New Near Extremal Black Holes and Love Symmetry
Alfredo Guevara, Uri Kol
Rotating and charged black holes are known to exhibit remarkable properties close to extremality, including emergent hidden symmetries and holographic duality to 2D theories. In th…
An Exact Black Hole Scattering Amplitude
Alfredo Guevara, Uri Kol, Huy Tran
General Relativity famously predicts precession of orbital motions in the Schwarzschild metric. In this paper we show that by adding a NUT charge the precession vanishes t…
Quantum Criticality in Black Hole Scattering
Uri Kol
The Teukolsky equation describing scattering from Kerr black holes captures a few important effects in the process of binary mergers, such as tidal deformations and the decay of ri…
Self Dual Black Holes as the Hydrogen Atom
Alfredo Guevara, Uri Kol
Rotating black holes exhibit a remarkable set of hidden symmetries near their horizon. These hidden symmetries have been shown to determine phenomena such as absorption scattering,…
