Emergent universe in Horava-Lifshitz-like F(R) gravity
M. Khodadi, Y. Heydarzade, F. Darabi +1
We investigate the Einstein static universe (ESU) and the emergent universe scenario in the framework of Hořava-Lifshitz-like gravity. We first perform a dynamical analysis…
Einstein static universe on the brane supported by extended Chaplygin gas
Y. Heydarzade, F. Darabi, K. Atazadeh
We study the cosmological models in which an extended Chaplygin gas universe is merged with the braneworld scenario. In particular, we examine the realization of Einstein static un…
Emergent Universe in the Braneworld Scenario
Y. Heydarzade, H. Hadi, F. Darabi +1
According to Padmanabhan's proposal, the difference between the surface degrees of freedom and the bulk degrees of freedom in a region of space may result in the acceleration of Un…
On the Stability of Einstein Static Universe in Doubly General Relativity Scenario
M. Khodadi, Y. Heydarzade, K. Nozari +1
By presenting a relation between average energy of the ensemble of probe photons and energy density of the Universe, in the context of {\it gravity's rainbow} or {\it doubly genera…
Deformed Horava-Lifshitz Cosmology and Stability of Einstein Static Universe
Y. Heydarzade, M. Khodadi, F. Darabi
Stability of the Einstein static universe versus the linear scalar, vector and tensor perturbations is investigated in the context of deformed Hořava-Lifshitz cosmology inspired by…
Entanglement Witnesses for Indistinguishable Particles
A. Reusch, J. Sperling, W. Vogel
We study the problem of witnessing entanglement among indistinguishable particles. For this purpose, we derive a set of equations which results in necessary and sufficient conditio…
