Does the Superluminal Neutrino Uncover Torsion?
M. B. Altaie
I investigate the possibility of the propagation of neutrino with superluminal speed through matter in the context of the relation between gravity, spin and torsion. Using a lemma…
A quantum black hole universe
M. B. Altaie
Using the result obtained in a prevoius paper, in which I found an upper limit on the region of particle creation in the vicinity of the event horizon of a Schwarzschild black hole…
The Friedmann Paradigm: A critical review
M. B. Altaie
The Friedmann paradigm for a dynamical universe emanating from a spacetime singularity is critically reviwed. Quantum effects, playing the essential role at the very early stages,…
A non-singular universe with vacuum energy
M. B. Altaie, U. Al-Ahmad
We construct a model for the universe based on the existence of quantum fields at finite temperature in the background of Robertson-Walker spacetime in presence of a non-zero cosmo…
Finite-temperature scalar fields and the cosmological constant in an Einstein universe
M. B. Altaie, M. R. Setare
We study the back reaction effect of massless minimally coupled scalar field at finite temperatures in the background of Einstein universe. Substituting for the vacuum expectation…
Back reaction of the neutrino field in an Einstein universe
M. B. Altaie
The back reaction effect of the neutrino field at finite temperature in the background of the static Einstein universe is investigated. A relationship between the temperature of th…
Casimir energy for spherical shell in Schwarzchild black hole background
M. R. Setare, M. B. Altaie
In this paper, we consider the Casimir energy of massless scalar field which satisfy Dirichlet boundary condition on a spherical shell. Outside the shell, the spacetime is assumed…
Back-reaction of Quantum fields in an Einstein Universe
M. B. Altaie
We study the back-reaction effects of the finite-temperature scalar field and the photon field in the background of an Einstein universe. In each case we find a relation between th…
Boson Condensation in an Einstein Universe
M. B. Altaie, Ehab Malkawi
In this paper we investigate the Bose-Einstein condensation of massive spin-1 particles in an Einstein universe. The system is considered under relativistic conditions taking into…
