Quantum Corrected Black Holes from String T-Duality — •Piero Nicolini1, 2, Euro Spallucci3, and Michael Wondrak1, 2 — 1Goethe Universität, Frankfurt — 2Frankfurt Institute for Advanced Studies — 3University of Trieste
After recalling the relation between the T-duality and the path integral duality, we present an exact static, neutral black hole solution emerging from the stringy modifications of Newton's potential. The spacetime is singularity free and formally equivalent to the Bardeen metric, apart from the presence of a string dependent ultraviolet regulator. Some considerations about the thermodynamics will be offered as a conclusion.
