Why Barriola--Vilenkin Global Monopoles Cannot Rotate?
Yi Lu, Xiao-Yin Pan, Meng-Yun Lai +1
The Barriola--Vilenkin global monopoles are topological defects predicted by certain grand unified theories and have been extensively studied for their astrophysical and cosmologic…
Finite-Distance Gravitational Lensing of a Global Monopole in a Schwarzschild-de Sitter Spacetime
Yi Lu, Xiao-Yin Pan, Meng-Yun Lai +1
We investigate the gravitational lensing of a Schwarzschild-de Sitter black hole with a global monopole at finite distances. In this asymptotically nonflat spacetime, the deflectio…
Field equations and particle motion in covariant emergent gravity
Yen-Kheng Lim, Qing-hai Wang
We derive the full set of field equations based on Hossenfelder's recent covariant formulation of the emergent gravity model, along with perturbative and exact solutions. The exact…
Criteria of existence for bounce solutions in false vacuum decay with gravity
Nicholas W. K. Wong, Jiangbin Gong, Yen-Kheng Lim +1
The bounce solutions of self-interacting scalar fields coupled to gravity are studied using a semi-classical approach. We found that bounce solutions have a maximum required barrie…
Exact gravitational lensing in conformal gravity and Schwarzschild-de Sitter spacetime
Yen-Kheng Lim, Qing-hai Wang
An exact solution is obtained for the gravitational bending of light in static, spherically symmetric metrics which includes the Schwarzschild-de Sitter spacetime and also the Mann…
