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…

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.…
