Black Hole Interior from Loop Quantum Gravity

Abstract EN

We calculate modifications to the Schwarzschild solution by using a semiclassical analysis of loop quantum black hole.

We obtain a metric inside the event horizon that coincides with the Schwarzschild solution near the horizon but that is substantially different at the Planck scale.

In particular, we obtain a bounce of the S2 sphere for a minimum value of the radius and that it is possible to have another event horizon close to the r=0 point.
