Casimir traversable wormholes in Gauss-Bonnet gravity
Mohammad Reza Mehdizadeh, Amir Hadi Ziaie
In this work, we study Casimir wormhole solutions and investigate satisfaction of energy conditions in the framework of Einstein-Gauss-Bonnet (EGB) gravity. We firstly find travers…
Gravitational Collapse of an Inhomogeneous Fluid in Rastall Theory
Akbar Jahan, Naser Sadeghnezhad, Amir Hadi Ziaie
We study spherically symmetric gravitational collapse of an inhomogeneous fluid with anisotropic energy momentum tensor (EMT) in Rastall gravity. Considering a linear equation of s…
Constraining fractionality using some observational tests
H. Moradpour, S. Jalalzadeh, R. Jalalzadeh +1
Recently, a fractional version of the Schwarzschild-Tangherlini black hole with a fractal horizon has been introduced. Motivated by the key role of the Schwarzschild solution in gr…
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…
Gamow Temperature in Tsallis and Kaniadakis Statistics
Hooman Moradpour, Mohsen Javaherian, Ebrahim Namvar +1
Relying on the quantum tunnelling concept and Maxwell-Boltzmann-Gibbs statistics, Gamow shows that the star-burning process happens at temperatures comparable to a critical value,…
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…
