Regular black hole with sub-Planckian curvature and suppressed exponential mass inflation
Zhong-Wen Feng, Hong-Lin Liu, Yi Ling +1
We construct a static spherically symmetric regular black hole with a Minkowski core, and a degenerate inner horizon with vanishing surface gravity. The spacetime contains a non-ex…
Symmetric black-to-white hole solutions with a cosmological constant
Zhong-Wen Feng, Qing-Quan Jiang, Yi Ling +2
For a system with a Hamiltonian constraint, we demonstrate that its dynamics is invariant under different choices of the lapse function, regardless of whether the Hamiltonian incor…
The new higher-order generalized uncertainty principle and primordial big bang nucleosynthesis
Song-Shan Luo, Zhong-Wen Feng
As an important class of quantum gravity models, the generalized uncertainty principle (GUP) plays an important role in exploring the properties of cosmology and its related proble…
Quasinormal modes of regular black holes with sub-Planckian curvature and Minkowskian core
Chen Tang, Yi Ling, Qing-Quan Jiang +1
We investigate the perturbation of the scalar field as well as the electromagnetic field over a sort of regular black holes which are characterized by the sub-Planckian curvature a…
