Cosmological evolution and dark energy in osculating Barthel-Randers geometry
Rattanasak Hama, Tiberiu Harko, Sorin V. Sabau +1
We consider the cosmological evolution in an osculating point Barthel-Randers type geometry, in which to each point of the space-time manifold an arbitrary point vector field is as…
Cosmological implications of Rastall- theory
Shahab Shahidi
Cosmological implications of a generalized Rastall theory where the non-conservation equation is promoted to accepts arbitrary functions of the Ricci scalar is considered. We have…
Non-minimal Energy-momentum squared gravity
Shahab Shahidi
We consider a gravitational theory with an additional non-minimal coupling between baryonic matter fields and geometry. The coupling is second order in the energy momentum tensor a…
Black hole solutions in modified gravity induced by quantum metric fluctuations
Jin-Zhao Yang, Shahab Shahidi, Tiberiu Harko +1
The inclusion of the quantum fluctuations of the metric in the geometric action is a promising avenue for the understanding of the quantum properties of gravity. In this approach t…
Cosmology in theories with derivative matter coupling
Zahra Haghani, Shahab Shahidi
A new class of modified gravity theories with a healthy higher order derivative terms of a function of the matter Lagrangian is considered. Generally the energy momentum t…
Cosmic acceleration via derivative matter couplings
Zahra Haghani, Shahab Shahidi
A gravitational theory with derivative matter coupling is proposed which adopt de Sitter expansion at late times with ordinary baryonic matter. Matter components are conserved sepa…
