摘要：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.
