In this paper we present some stringy corrections to black hole spacetimes emerging from string T-duality. 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 introduce 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 to derive a consistent black hole metric for the spherically symmetric, electrically neutral case. It turns out that the new spacetime is regular and is formally equivalent to the Bardeen metric, apart from a different ultraviolet regulator. On the thermodynamics side, the Hawking temperature admits a maximum before a cooling down phase towards a thermodynamically stable end of the black hole evaporation process. The findings support the idea of universality of quantum black holes.

  1. Horizon formation from effective matter profiles in static spacetimes

    gr-qc 2026-05 unverdicted novelty 5.0 of 10

    Sufficient conditions are given for a unique outer horizon to cloak a negative-mass Schwarzschild timelike naked singularity when non-negative localized anisotropic matter is added.

  2. Regular Rotating Black Hole: Probing the boundaries of the Radiative Signatures and Jet Power

    astro-ph.HE 2025-08 conditional novelty 5.0 of 10

    MOG regular rotating black holes are compatible with most X-ray binary data only for beta below about 0.38 to 0.4, and are excluded for the near-extremal source GRS 1915+105.

  3. Gravitational perturbations of a regular T-duality inspired black hole: Quasinormal modes, excitation factors, and time-domain evolution

    gr-qc 2026-07 conditional novelty 4.0 of 10

    Gravitational quasinormal-mode frequencies of a T-duality-inspired regular black hole are computed, showing the zero-point length makes the ringdown oscillate faster and alters damping non-monotonically.

  4. Observational constraints on the modified cosmology inspired by string T-duality

    gr-qc 2025-10 conditional novelty 4.0 of 10

    Late-time data bound the T-duality zero-point-length coupling to β ≲ 10^-3, leaving ΛCDM statistically equivalent.
