Dynamical thin shells in black hole ringdown
Han-Wen Hu, Chen Lan, Zong-Kuan Guo
We study how a radially oscillating thin shell outside a black hole (BH) affects gravitational wave ringdown and derive matching conditions for polar and axial perturbations from t…
Symmetry preservation in black hole quasinormal mode spectra
Han-Wen Hu, Chen Lan, Zong-Kuan Guo +1
We establish a general relation between symmetries of gravitational theories and black hole (BH) quasinormal mode (QNM) spectra. We show that a symmetry implies isospectrality when…
Parity violating spectral dynamics of black holes in dynamical Chern-Simons gravity
Han-Wen Hu, Chen Lan, Zong-Kuan Guo
We study how environmentally driven spectral instabilities of quasinormal modes respond to parity violating gravito-scalar coupling in black holes. Focusing on dynamical Chern-Simo…
Quantum Corrected Geodesic Motion in Polymer Kerr-like Spacetime
Zhiyang Guo, Chen Lan, Yan Liu
Rotating black holes are prevalent in astrophysical observations, and a Kerr-like solution that incorporates quantum gravity effects is essential for constructing realistic models.…
Pseudo-hermitian Chebyshev differential matrix and non-Hermitian Liouville quantum mechanics
Chen Lan, Wei Li, Huifang Geng
The spectral collocation method (SCM) exhibits a clear superiority in solving ordinary and partial differential equations compared to conventional techniques, such as finite differ…
