Assuming the RG parameter $\\tilde{\\omega}$ is fixed to its phenomenologically motivated value, we treat the interpolation parameter $\\gamma$ as free and investigate how it modifies the black hole's response to axial gravitational perturbations. Quasinormal frequencies are computed using the sixth-order WKB method with Pad\\'e approximants, and their dependence on $\\gamma$ and the black hole mass $M$ is analyzed. We find that the Schwarzschild limit is rapidly recovered for large $M$ or large $\\gamma$, while significant deviations arise in the quantum regime. The accuracy of the WKB results is confirmed by time-domain integration of the wave equation. Comparison of grey-body factors computed via both the WKB method and the quasinormal mode correspondence are in a good concordance. Our findings indicate that quantum corrections can leave significant imprints in the ringdown and radiation spectra, while preserving consistency with classical results in the appropriate limit.","external_url":"https://arxiv.org/abs/2507.07196","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-10T14:47:14.035796+00:00","pith_arxiv_id":"2507.07196","created_at":"2026-05-10T10:49:56.457575+00:00","updated_at":"2026-07-10T14:47:14.035796+00:00","title_quality_ok":true,"display_title":"Bolokhov and M","render_title":"Bolokhov and M"},"hub":{"state":{"work_id":"7779c442-5558-4a76-8d06-8af4b42bb276","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":22,"external_cited_by_count":null,"distinct_field_count":1,"first_pith_cited_at":"2025-12-29T14:47:19+00:00","last_pith_cited_at":"2026-07-08T22:22:08+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-23T07:29:41.621733+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":11},{"context_role":"method","n":1}],"polarity_counts":[{"context_polarity":"background","n":9},{"context_polarity":"unclear","n":2},{"context_polarity":"use_method","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
