Real Part Emergence in Purely Imaginary Quasinormal Modes in Perturbed de Sitter Braneworlds
Hai-Long Jia, Wen-Di Guo, Yun-Tao Gu +1
For braneworlds with infinite extra dimensions, an analysis of the stability of the characteristic spectrum is essential for understanding their dynamical properties. In this study…
Stringy Effects on Holographic Complexity: The Complete Volume in Dynamical Spacetimes
Qi Yang, Yu-Xiao Liu
We investigate the stringy effects on holographic complexity in -dimensional Gauss-Bonnet gravity using the ``complete volume'' proposal for higher-curvature theories. Our a…
Gravitational-Bumblebee perturbations: Exact decoupling and isospectrality
Hui-Fa Liu, Wentao Liu, Yu-Xiao Liu +2
In this paper, we present the exact decoupling of the full metric and bumblebee field perturbations in a Schwarzschild-like background. The coupled system reduces to four decoupled…
Macroscopic Optical Nonreciprocity: A Black Hole as an Optical Diode
Wentao Liu, Di Wu, Xiongjun Fang +2
Optical reciprocity--the principle that light retraces the same path when source and detector are interchanged--is a foundational concept in geometric optics. In this Letter, we de…
Gravitational wave polarization modes and stability analysis in Weyl geometry gravity
Yu-Zhi Fan, Xiao-Bin Lai, Yu-Qi Dong +1
We investigate the gravitational wave polarization modes and stability in Weyl geometry gravity within a Minkowski background. Our results indicate that the tensor sector consists…
Cosmological perturbations and gravitational waves in the general Einstein-vector theory
Xiao-Bin Lai, Yu-Zhi Fan, Yu-Qi Dong +1
We investigate the stability and gravitational waves (GWs) in the four-dimensional general Einstein-vector theory on a cosmological background. To study the stability, we systemati…
Quasinormal modes of thick branes in gravity
Yu-Peng E, Chun-Chun Zhu, Yu-Xiao Liu
We systematically investigate the quasinormal modes of thick branes in gravity by numerically solving the Schrödinger-like perturbation equation of gravitational perturbatio…
A Universal Framework for Horizon-Scale Tests of Gravity with Black Hole Shadows
Wentao Liu, Yang Liu, Di Wu +1
In this Letter, we have developed a numerically efficient framework for evaluating parameters in metric theories of gravity, and applied it to constrain the horizon-scale magnetic…
Quasinormal modes of an electrically charged Kalb-Ramond black hole
Yun-Tao Gu, Wen-Di Guo, Yu-Xiao Liu
Lorentz violation serves as a significant feature in many modified theories of gravity. In particular, spontaneous Lorentz violation induced by the Kalb-Ramond field has attracted…
Quasinormal modes of a charged spherically symmetric black hole in bumblebee gravity
Bo-Rui Li, Jia-Zhou Liu, Wen-Di Guo +1
Recently, exact charged spherically symmetric black hole solutions within the framework of bumblebee gravity have been obtained, where the Lorentz symmetry is spontaneously broken…
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 exp…
Gravitational Echoes from Braneworlds
Chun-Chun Zhu, Jing Chen, Wen-Di Guo +1
Gravitational echoes can be used to probe the structure of spacetime. In this paper, we investigate the gravitational echoes in different braneworld models in five-dimensional spac…
Parameterized quasinormal frequencies and Hawking radiation for axial gravitational perturbations of a holonomy-corrected black hole
Sen Yang, Wen-Di Guo, Qin Tan +2
As the fingerprints of black holes, quasinormal modes are closely associated with many properties of black holes. Especially, the ringdown phase of gravitational waveforms from the…
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 ef…
