Geometric resolution of the Schwarzschild horizon
Ibrahima Bah, Pierre Heidmann
Abstract
We provide the first example of a geometric transition that resolves the Schwarzschild black hole into a smooth microstructure in eleven-dimensional supergravity on a seven-torus. The geometry is indistinguishable from a Schwarzschild black hole dressed with a scalar field in four dimensions, referred to as a Schwarzschild scalarwall. In eleven dimensions, the scalar field arises as moduli of the torus. The resolution occurs at an infinitesimal scale above the horizon, set by the size of the internal torus, where it transitions to a smooth bubbling spacetime supported by M2-brane flux.
