Spectral Butterfly Effect and Resilient Ringdown in Thick Braneworlds
Hai-Long Jia, Wen-Di Guo, Yu-Peng Zhang +1
The quasinormal mode spectrum is a unique fingerprint linking gravitational-wave observations to extra-dimensional geometry. In this Letter, we show that thick braneworlds exhibit…
Quasinormal modes of the thick braneworld in gravity
Zi-Jie Li, Hai-Long Jia, Qin Tan +1
We investigate the quasinormal modes (QNMs) of a thick brane model in gravity with . Requiring the energy density to remain positive and the scalar field t…
Quasinormal ringing of thick braneworlds with a finite extra dimension
Hai-Long Jia, Wen-Di Guo, Qin Tan +1
In this work, we investigate the quasinormal modes of the Poincaré thick brane with a finite extra dimension. Unlike the case with an infinite extra dimension, the gravitational e…
Quasinormal Ringing of de Sitter Braneworlds
Hai-Long Jia, Wen-Di Guo, Yu-Xiao Liu +1
Compared with the Poincaré braneworld, the de Sitter (dS) braneworld aligns more closely with the present universe characterized by a small but finite cosmological constant. To ex…
