We construct a sort of regular black holes with a sub-Planckian Kretschmann scalar curvature. The metric of this sort of regular black holes is characterized by an exponentially suppressing gravity potential as well as an asymptotically Minkowski core. In particular, with different choices of the potential form, they can reproduce the metric of Bardeen/Hayward/Frolov black hole at large scales. The heuristical derivation of this sort of black holes is performed based on the generalized uncertainty principle over curved spacetime which includes the effects of tidal force on any object with finite size which is bounded below by the minimal length.

  1. Tidal Love numbers for regular black holes

    gr-qc 2025-12 unverdicted novelty 6.0

    Tidal Love numbers of regular black holes are generically nonzero, model-dependent, and can acquire logarithmic scale dependence at higher perturbative orders.

  2. Regular black hole with sub-Planckian curvature and suppressed exponential mass inflation

    gr-qc 2026-05 unverdicted novelty 5.0

    A regular black hole metric is constructed with sub-Planckian curvature controlled by the inner horizon radius and power-law rather than exponential mass inflation near the inner horizon.

  3. Gravitational waveforms from periodic orbits around a novel regular black hole

    gr-qc 2025-09 unverdicted novelty 5.0

    Numerical study finds that a deviation parameter in a regular black hole with Minkowski core produces phase shifts and amplitude changes in kludge waveforms from periodic orbits, making them distinguishable from Schwa...
