Radial spectra and dynamical signatures of excited boson stars
Chen-Hao Hao, Wen-Di Guo, Qin Tan +1
We compute the lowest radial mode of spherically symmetric boson stars along equilibrium branches with a fixed number of radial nodes, considering both mini boson stars and quartic…
Transverse electric waves in Bandos-Lechner-Sorokin-Townsend nonlinear electrodynamics
Yang Shi, Qinyan Tan, Towe Wang
In the generalized Born-Infeld electrodynamics discovered by Bandos, Lechner, Sorokin and Townsend, we study transverse electric waves propagating perpendicular to a constant magne…
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…
Evolution of Fermion Resonance in Thick Brane
Chun-Chun Zhu, Qin Tan, Yu-Peng Zhang +1
In this work, we investigate numerical evolution of massive Kaluza-Klein (KK) modes of a Dirac field on a thick brane. We deduce the Dirac equation in five-dimensional spacetime, a…
Quasinormal modes and greybody factor of a Lorentz-violating black hole
Wen-Di Guo, Qin Tan, Yu-Xiao Liu
Recently, a static spherically symmetric black hole solution was found in gravity nonminimally coupled a background Kalb-Ramond field. The Lorentz symmetry is spontaneously broken…
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…
