In this paper, we present a family of regular black hole solutions in the
presence of charge and angular momentum. We also discuss the related
thermodynamics and we comment about the black hole life cycle during the
balding and spin down phases. Interestingly the static solution resembles the
Ay\’on-Beato–Garc\’ia spacetime, provided the T-duality scale is redefined in
terms of the electric charge, $l_0\to Q$. The key factor at the basis of our
derivation is the employment of Padmanabhan’s propagator to calculate static
potentials. Such a propagator encodes string T-duality effects. This means that
the regularity of the spacetimes here presented can open a new window on string
theory phenomenology.
