Dynamic wormhole solutions in Einstein-Cartan gravity
Mohammad Reza Mehdizadeh, Amir Hadi Ziaie
In the present work we investigate evolving wormhole configurations described by a constant redshift function in Einstein-Cartan theory ({\sf ECT}). The matter content consists of…
Static Vacuum Solutions on Curved Spacetimes with Torsion
Hamid Shabani, Amir Hadi Ziaie
The Einstein-Cartan-Kibble-Sciama ({\sf ECKS}) theory of gravity naturally extends Einstein\rq{}s general relativity ({\sf GR}) to include intrinsic angular momentum (spin) of matt…
Bouncing cosmological solutions from f(R,T) gravity
Hamid Shabani, Amir Hadi Ziaie
In this work we study classical bouncing solutions in the context of gravity in a flat {\sf FLRW} background using a perfect fluid as the on…
Einstein-Cartan wormhole solutions
Mohammad Reza Mehdizadeh, Amir Hadi Ziaie
In the present work we investigate wormhole structures and the energy conditions supporting them, in Einstein-Cartan theory ({\sf ECT}). The matter content consists of a Weyssenhof…
Interpretation of gravity in terms of a conserved effective fluid
Hamid Shabani, Amir Hadi Ziaie
In the present work we introduce a novel approach to study gravity theory from a different perspective. Here, denotes the trace of energy-momentum te…
Late-time cosmological evolution of a general class of f(R, T) gravity with minimal curvature-matter coupling
Hamid Shabani, Amir Hadi ziaie
In this work, we study the late-time cosmological solutions of f(R,T)=g(R)+h(-T) models assuming that the conservation of the energy-momentum tensor (EMT) is violated. We perform o…
Consequences of energy conservation violation: Late time solutions of subclass of gravity using dynamical system approach
Hamid Shabani, Amir Hadi Ziaie
Very recently, the authors of [PRL {\bf 118} (2017) 021102] have shown that violation of energy-momentum tensor (EMT) could result in an accelerated expansion state via appearing a…
