In this letter we present some stringy corrections to black hole spacetimes emerging from string Tduality. As a first step, we derive the static Newtonian potential by exploiting the relation between the T-duality and the path integral duality. We show that the intrinsic non-perturbative nature of stringy corrections introduces an ultraviolet cutoff known as zero-point length in the path integral duality literature. As a result, the static potential is found to be regular. We use this result todoi:10.1016/j.physletb.2019.134888 fatcat:z6izdnwvjvhb3k7cxuopd6hzly
