Particle creation in the framework of f(G) gravity
R. Rashidi, F. Ahmadi, M. R. Setare
In this paper, we study the problem of massless particle creation in a flat, homogeneous and isotropic universe in the framework of gravity. The Bogolyubov coefficients are…
Hubble Diagrams in the Jordan and Einstein Frames
Reza Rashidi
Different models in cosmology generally predict different Hubble diagrams. Then, the comparison between the Hubble diagrams may be used as a way for distinguishing between differen…
Generalized Uncertainty Principle Removes The Chandrasekhar Limit
Reza Rashidi
The effect of a generalized uncertainty principle on the structure of an ideal white dwarf star is investigated. The equation describing the equilibrium configuration of the star i…
Removing the Big Bang Singularity: The role of the generalized uncertainty principle in quantum gravity
Reza Rashidi
The possibility of avoiding the big bang singularity by means of a generalized uncertainty principle is investigated. In relation with this matter, the statistical mechanics of a f…
Unruh's detector in the presence of Lorentz symmetry breaking
R. Rashidi, N. Khosravi, E. Khajeh +1
We investigate the quantum field theory of a Lorentz non-invariant model with a massive nonlinear dispersion relation in Minkowski space. The model involves some non-causal signals…
On the gravitational coupling of Hadamard states
Hadi Salehi, Parvin Moyassari, Reza Rashidi
We study the constraints imposed by the Hadamard condition on the two-point function of local states of a scalar quantum field conformally coupled to a gravitational background. We…
