Generic isolated horizons in loop quantum gravity

Understand

Isolated horizons model equilibrium states of classical black holes.

• A detailed quantization, starting from a classical phase space restricted to spherically symmetric horizons, exists in the literature and has since been extended to axisymmetry.
• This paper extends the quantum theory to horizons of arbitrary shape.
• Surprisingly, the Hilbert space obtained by quantizing the full phase space of \textit{all} generic horizons with a fixed area is identical to that originally found in spherical symmetry.
