New generalization of the Barboza-Alcaniz parametrization of Dark energy
Shahab Shahidi
A generalization of the Barboza-Alcaniz parametrization of dark energy is proposed. This is a three-parameter model which can resolve the shortcomings of the Barboza-Alcaniz behavi…

Dark energy and accelerating cosmological evolution in a Universe with a Weylian boundary
Tiberiu Harko, Shahab Shahidi
We investigate the influence of boundary terms in gravitational field theories, by considering that in the Einstein-Hilbert action the boundary can be described by a non-metric Wey…

Dark energy and a new realization of the matter Lagrangian
Shahab Shahidi, Sedigheh Farahzad
A new realization of the matter Lagrangian is introduced which models the dark energy component as a non-standard combination of thermodynamics quantities of the baryonic matter. W…
