We examine the quasi normal modes of Ellis-Bronnikov wormholes embedded in a warped five dimensional braneworld background and compare with it's four dimensional counterpart. These scalar quasi normal frequencies are obtained using the WKB formula, Prony method and the direct integration method. The signature of the warped extra dimension shows up as two distinct quasi normal ringing era, characterised by two distinct dominant quasi normal modes. Features of the latter region are similar to that observed earlier for massive scalar field in black hole background. We also discuss the how steepness of the neck of the wormhole effects the quasi normal frequencies.

  1. Quasinormal modes and grey-body factors of Morris-Thorne wormholes

    gr-qc 2024-12 reject novelty 6.0 of 10

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

  2. 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.
