In this paper, we investigate the quasinormal mode (QNM) spectra for scalar perturbation over a quantum-corrected black hole (BH). The fundamental modes of this quantum-corrected BH exhibit two key properties. Firstly, there is a non-monotonic behavior concerning the quantum-corrected parameter for zero multipole number. Secondly, the quantum gravity effects result in slower decay modes. For higher overtones, a significant deviation becomes evident between the quasinormal frequencies (QNFs) of the quantum-corrected and Schwarzschild BHs. The intervention of quantum gravity corrections induces a significant outburst of overtones. This outburst of these overtones can be attributed to the distinctions near the event horizons between the Schwarzschild and quantum-corrected BHs. Therefore, overtones can serve as a means to probe physical phenomena or disparities in the vicinity of the event horizon.

    Sixth-order WKB formulas for wormhole quasinormal modes and grey-body factors are presented, but the grey-body factor part is internally inconsistent.

    A quantum-corrected Schwarzschild black hole is shown to be stable under scalar and electromagnetic perturbations, with thermodynamic topology identical to Reissner-Nordström.

  5. Correspondence between quasinormal modes and grey-body factors for massive fields in Schwarzschild-de Sitter spacetime

    gr-qc 2024-12 conditional novelty 4.0 of 10

    For massive scalar fields around de Sitter black holes, grey-body factors computed from quasinormal modes agree with direct WKB calculations to high precision, even for low multipoles.

  6. Correspondence between quasinormal modes and grey-body factors of spherically symmetric traversable wormholes

    gr-qc 2024-12 conditional novelty 4.0 of 10

    For three families of traversable wormholes, the authors verify that the WKB correspondence between quasinormal modes and grey-body factors, known for black holes, holds to second order beyond the eikonal limit.
