Signature quasinormal modes of Ellis-Bronnikov wormhole embedded in warped braneworld background

We examine the quasinormal modes of Ellis-Bronnikov wormholes embedded in a warped five-dimensional braneworld background and compare with its four-dimensional counterpart. These scalar quasinormal 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 quasinormal ringing eras, characterized by two distinct dominant quasinormal modes. Features of the latter region are similar to that observed earlier for massive scalar fields in the black hole background, particularly the existence of arbitrarily long-lived quasinormal modes. We also discuss the how steepness of the neck of the wormhole effects the quasinormal frequencies.
