The quantum Oppenheimer-Snyder model for higher-dimensional spacetimes is studied. The higher-dimensional quantum-corrected Schwarzschild black hole is obtained by the junction condition. It turns out that quantum bounces always occur in the collapse thus that the classical gravitational collapse singularities are avoided. The scalar perturbations upon the quantum-corrected black holes are also studied. It turns out that the quantum corrections enhance the oscillation frequency in lower dimensions and decrease it in higher dimensions. Moreover, the thermodynamic laws of the quantum-corrected black holes imply that the Hawking temperature of quantum-corrected black hole decreases as the mass decreases in contrast to the classical situation. The behaviour of heat capacity indicates that quantum corrections introduce an extra phase transition of the black holes.

  1. Asymmetric Quantum Oppenheimer-Snyder Collapse

    gr-qc 2026-08 conditional novelty 6.0 of 10

    Asymmetric loop-quantum-cosmology collapse of a dust ball yields a geodesically complete, bouncing regular black hole spacetime with a C^0 shock at the dust surface and two joined vacuum geometries.

  2. Dust shell in effective loop quantum black hole model

    gr-qc 2025-06 conditional novelty 6.0 of 10

    In a polymerized loop-quantum-gravity black hole model, a collapsing dust shell bounces and, for sufficiently heavy shells, follows a spacelike trajectory through the horizon, implying a finite horizon lifetime and a ...

  3. Evaporation and fate of covariant quantum black holes

    gr-qc 2026-07 conditional novelty 5.0 of 10

    For a covariant LQG black-hole metric, Hawking mass-loss rates depend on emitted-particle spin and deviate from Schwarzschild rates only for sub-Planckian masses.
