Black holes and covariance in effective quantum gravity: A solution without Cauchy horizons
Cong Zhang, Jerzy Lewandowski, Yongge Ma +1
The issue of general covariance in effective quantum gravity models within the Hamiltonian framework is addressed. The previously proposed equations for the covariance condition in…
Black Holes and Covariance in Effective Quantum Gravity
Cong Zhang, Jerzy Lewandowski, Yongge Ma +1
The longstanding issue of general covariance in effective models of quantum gravity is addressed, which arises when canonical quantum gravity leads to a semiclassical model describ…
Covariant effective spacetimes of spherically symmetric electrovacuum with a cosmological constant
Jinsong Yang, Cong Zhang, Yongge Ma
An algebraic framework was introduced in our previous works to address the covariance issue in spherically symmetric effective quantum gravity. This paper extends the framework to…
Shadows of rotating black holes in effective quantum gravity
Zhenglong Ban, Jiawei Chen, Jinsong Yang
Recently, two new spherically symmetric black hole models with covariance have been proposed in effective quantum gravity. Based on these models, we use the modified Newman-Janis a…
