Quantum Corrected Black Holes from String T-Duality — •Piero Nicolini^{1, 2}, Euro Spallucci³, and Michael Wondrak^{1, 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.
