Noncommutative nonsingular black holes

Research output: Contribution to journalConference articlepeer-review


Adopting noncommutative spacetime coordinates, we determined a new solution of Einstein equations for a static, spherically symmetric matter source. The limitations of the conventional Schwarzschild solution, due to curvature singularities, are overcome. As a result, the line element is endowed of a regular DeSitter core at the origin and of two horizons even in the considered case of electrically neutral, nonrotating matter. Regarding the Hawking evaporation process, the intriguing new feature is that the black hole is allowed to reach only a finite maximum temperature, before cooling down to an absolute zero extremal state. As a consequence the quantum back reaction is negligible.
