Hawking evaporation and the possibility of remnant formation for covariant quantum black holes
Li-Shuai Wang, Xiangdong Zhang
Covariant quantum black holes (BHs) are an important development in loop quantum gravity (LQG), and investigations of their evaporation may offer a possible avenue for testing LQG.…
Critical collapse of a self-interacting scalar field in asymptotically anti-de Sitter spacetime
Li-Jie Xin, Xiangdong Zhang
We study the critical gravitational collapse of a spherically symmetric massless scalar field in asymptotically anti-de Sitter (AdS) spacetime. The scalar field potential adopted h…
Stress-energy tensor of quantized scalar fields in thermal states on a zero-tidal wormhole
Shun Jiang, Xiangdong Zhang
The construction of a static traversable wormhole requires exotic matter that satisfies the Morris-Thorne conditions. Quantum energy-momentum tensors have long been considered the…
Non-singular Inflation-Dark Energy Unification Model Based on Loop Quantum Cosmology and Mass-Varying Neutrinos
Zhiming Shuai, Xiangdong Zhang
Unifying the early-universe inflationary paradigm with late-time cosmic acceleration, while resolving the initial Big Bang singularity, remains one of the most profound challenges…
Distinguishability of magnetic massive black holes from environmental mimics with inspiral gravitational waves
Xulong Yuan, Xiangdong Zhang
In this work, we investigate the ppE waveform imprints induced by the external magnetic fields of Bertotti-Robinson and Bonnor-Melvin black holes, with the aim of distinguishing su…
Quantum Oppenheimer-Snyder primordial black holes as all the dark matter
Li-Shuai Wang, Xiangdong Zhang
Primordial black holes (PBHs) are widely considered as candidates for dark matter in many recent studies, and they are often modeled as Schwarzschild or Kerr black holes (BHs), whi…
Periodic orbits and gravitational waveforms of black holes in bumblebee gravity
Zijian Shi, Xiangdong Zhang, Yunlong Liu
In this paper, we investigate the dynamics of massive particles and the associated gravitational waveforms in the spacetime of a black hole within the framework of Einstein-Bumbleb…
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.…
Analytic solutions for the motion of spinning particles near brane-world black hole
Yunlong Liu, Xiangdong Zhang
The general motion of spinning test particles to the leading order approximation of spin in the brane-world spacetime is investigated. Analytical integrations for the equations of…
Gravitational waves for eccentric extreme mass ratio inspirals of self-dual spacetime
Yunlong Liu, Xiangdong Zhang
In this paper, we calculate the frequencies of geodesic orbits in self-dual spacetime on the equatorial plane and obtain the leading-order effects of loop quantum parameters on…
