Trace anomaly contributions to semi-classical wormhole geometries
Mohammad Reza Mehdizadeh, Amir Hadi Ziaie, Francisco S. N. Lobo
We investigate wormhole solutions within the framework of the semi-classical Einstein equations in the presence of the conformal anomaly (or trace anomaly). These solutions are sou…
Singularity Avoidance in Gravitational Collapse of an Inhomogeneous Fluid in Rastall Gravity
Akbar Jahan, Halime Miraghaei, Shayesteh Ghaffari +1
Various types of inhomogeneous collapse models in general relativity (GR) lead to the formation of spacetime singularities either visible or hidden by a spacetime horizon. Our aim…
Novel Brans-Dicke Wormhole Solutions in Non-Vacuum Spacetimes
Amir Hadi Ziaie, Naser Sadeghnezhad, Akbar Jahan
In the present study we search for a new class of wormhole solutions in the framework of Brans-Dicke (BD) theory in the presence of anisotropic matter distribution. Considering a l…
