Instability of QCD ghost dark energy model
Esmaeil Ebrahimi, Ahmad Sheykhi
We investigate the instability of the ghost dark energy model against perturbations in different cases. To this goal we use the squared sound speed whose sign determines th…
Interacting Ghost Dark Energy in Brans-Dicke Theory
Esmaeil Ebrahimi, Ahmad Sheykhi
We investigate the QCD ghost model of dark energy in the framework of Brans-Dicke cosmology. First, we study the non-interacting ghost dark energy in a flat Brans-Dicke theory. In…
Tachyon Reconstruction of Ghost Dark Energy
A. Sheykhi, M. Sadegh Movahed, E. Ebrahimi
Recently it has been argued that a possible source for the dark energy may arise due to the contribution to the vacuum energy of the QCD ghost in a time-dependent background. In th…
Scalar Field Reconstruction of Power-Law Entropy-Corrected HDE
Esmaeil Ebrahimi, Ahmad Sheykhi
A so called "power-law entropy-corrected holographic dark energy" (PLECHDE) was recently proposed to explain the dark energy dominated universe. This model is based on the power-la…
Magnetic Branes in Brans-Dicke-Maxwell Theory
A. Sheykhi, E. Ebrahimi
We present a new class of magnetic brane solutions in -dimensional Brans-Dicke-Maxwell theory in the presence of a quadratic potential for the scalar field. These solutions…
-Dimensional Lorentzian Wormholes in an Expanding Cosmological Background
E. Ebrahimi, N. Riazi
We discuss -dimensional dynamical wormholes in an evolving cosmological background with a throat expanding with time. These solutions are examined in the general relativity…
Expanding -Dimensional Wormhole Solutions in Brans-Dicke Cosmology
E. Ebrahimi, N. Riazi
We have obtained two classes of -dimensional wormhole solutions using a traceless energy-momentum tensor in Brans-Dicke theory of gravity. The first class contains wormhole…
