Quantum gravity effects in Myers-Perry space-times

Understand

We study quantum gravity effects for Myers-Perry black holes assuming that the leading contributions arise from the renormalization group evolution of Newton's coupling.

• Provided that gravity weakens following the asymptotic safety conjecture, we find that quantum effects lift a degeneracy of higher-dimensional black holes, and dominate over kinematical ones induced by rotation, particularly for small black hole mass, large angular momentum, and higher space-time dimensionality.
• Quantum-corrected space-times display inner and outer horizons, and show the existence of a black hole of smallest mass in any dimension.
• Ultra-spinning solutions no longer persist.
