Quasinormal modes and tidal Love numbers of covariant effective quantum black holes with cosmological constant
Yunlong Liu, Xiangdong Zhang
This paper systematically investigates the quasinormal modes (QNMs) and tidal Love numbers of covariant quantum-modified black holes (BHs) within two cosmological constant-dependen…

Particle Deflections around Microscopic Loop Quantum Black Holes with Rigorous Quantum Parameters
Haida Li, Xiangdong Zhang
The detection of quantum gravity effects is highly limited in both macroscopic and microscopic scenarios: The small quantum parameter makes most large-scale observations practicall…

Spinning Particle Dynamics and ISCO in Covariant Loop Quantum Gravity
Yongbin Du, Yunlong Liu, Xiangdong Zhang
In this paper, we investigate the motion of spinning particles in the background of covariant loop quantum gravity black holes, focusing on two distinct effective metric solutions.…
