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…

On Controlled Frames in Hilbert -modules

Mehdi Rashidi-Kouchi, Asghar Rahimi

In this paper, we introduce controlled frames in Hilbert -modules and we show that they share many useful properties with their corresponding notions in Hilbert space. Next, w…

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…
