Asymptotically-flat Black holes in Bumblebee gravity: Exact solutions and Thermodynamics
Jinbo Yang, Zhan-Feng Mai, Dicong Liang +1
We construct analytic solutions to the bumblebee gravity theory in static and spherically symmetric spacetimes, where the bumblebee vector field admits only a non-vanishing tempora…
On Coordinate Singularities Induced by Trapping Horizons
Jinbo Yang, Hongwei Tan, Hyat Huang +1
The trapping (or apparent) horizon serves as a key tool for tracing the complete evolution of black holes. We investigate a class of coordinate singularities induced by such trappi…
Thermodynamics of EMD-AdS black hole with deformed horizon
Yusheng Z. He, Jia-Hui Huang, Jinbo Yang
We show that the horizon shapes of static Einstein-Maxwell-dilaton (EMD) black holes can be deformed through an approach analogous to those observed in novel topological black hole…
Hairy Black Holes with Arbitrary Small Areas
Xiao-Ping Rao, Hyat Huang, Jinbo Yang
We obtained new hairy black hole solutions in Einstein-scalar theory, including asymptotic flat, de Sitter and anti-de Sitter black holes. The theory is inspired by Ref. [1], where…
Scale Invariant Extension of the Standard Model: A Nightmare Scenario in Cosmology
Mayumi Aoki, Jisuke Kubo, Jinbo Yang
Inflationary observables of a classically scale invariant model, in which the origin of the Planck mass and the electroweak scale including the right-handed neutrino mass is chiral…
A trick for calculating surface gravities of Killing horizons
Jinbo Yang
We propose a trick for calculating the surface gravity of the Killing horizon, especially for cases of rotating black holes. By choosing nice slices, the surface gravity and angula…
Light Ring behind Wormhole Throat: Geodesics, Images and Shadows
Hyat Huang, Jutta Kunz, Jinbo Yang +1
The geodesics of the Ellis-Bronnikov wormhole with two parameters are studied. The asymmetric wormhole has only one light ring and one innermost stable circular orbit located on on…
Novel topological black holes from thermodynamics and deforming horizons
Jinbo Yang
Two novel topological black hole exact solutions with unusual shapes of horizons in the simplest holographic axions model, the four-dimensional Einstein-Maxwell-axions theory, are…
Inflation and dark matter after spontaneous Planck scale generation by hidden chiral symmetry breaking
Mayumi Aoki, Jisuke Kubo, Jinbo Yang
Dynamical chiral symmetry breaking in a QCD-like hidden sector is used to generate the Planck mass and the electroweak scale including the heavy right-handed neutrino mass. A real…
Trapping Horizons of the Evolving Charged Wormhole and Black Bounce
Jinbo Yang, Hyat Huang
We obtain one family of dynamic solutions in the Einstein-Maxwell-scalar(EMS) theory. Our solutions could describe the evolving charged black(white) hole or wormhole and its transi…
Bronnikov-like Wormholes in Einstein-Scalar Gravity
Hyat Huang, Hong Lü, Jinbo Yang
In this paper, we analyse the global structure of the Bronnikov wormhole, which is the most general spherically-symmetric and static solution in Einstein gravity coupled to a free…
Charged Ellis Wormhole and Black Bounce
Hyat Huang, Jinbo Yang
By replacing the scalar with in the solution constructed in Ref\cite{Huang:2019lsl}, we obtain electrically-charged wormhole and black hole solutions in the Einstein-Maxwe…

Hongwei Tan, Jinbo Yang, Jingyi Zhang +1
In this paper, we show that the global monopole spacetime is one of the exact solutions of Einstein equations by means of the method treating the matter field as a non-linear sigma…

Jinbo Yang, Hongwei Tan, Tangmei He +1
We apply thermodynamics method to generate exact solution with maximum symmetric surface for Einstein equation without solving it. The exact solutions are identified with which peo…
A modified thermodynamics method to generate exact solutions of the Einstein equations
Hong-Wei Tan, Jin-Bo Yang, Tang-Mei He +1
We modify the method to generate the exact solutions of the Einstein equations basing on the laws of thermodynamics. Firstly, the Komar mass is used to take the place of the Misner…
