Emergence and expansion of cosmic space as due to M0-branes
Alireza Sepehri, Mohammad Reza Setare, Salvatore Capozziello
Recently, Padmanabhan [arXiv:1206.4916 [hep-th]] discussed that the difference between the number of degrees of freedom on the boundary surface and the number of degrees of freedom…
Cosmology from quantum potential in a system of oscillating branes
Alireza Sepehri
Recently, some authors proposed a new mechanism which gets rid of the big-bang singularity and shows that the age of the universe is infinite. In this paper, we will confirm their…
Cosmology from quantum potential in brane-anti-brane system
Alireza Sepehri
Recently, some authors removed the big-bang singularity and predicted an infinite age of our universe. In this paper, we show that the same result can be obtained in string theory…
Unifying inflation with late-time acceleration in BIonic system
Alireza Sepehri, Farook Rahaman, Mohammad Reza Setare +3
In this research, we propose a new model that allows to unify inflation, deceleration and acceleration phases of expansion history in BIonic system. In this model, in the beginning…
Holographic Cosmology from a System of M2-M5 Branes
Alireza Sepehri, Mir Faizal, Mohammad Reza Setare +1
In this paper, we analyze the holographic cosmology using a M2-M5 brane configuration. In this configuration, a M2-brane will be placed in between a M5-brane and an anti-M5-brane.…
A bridge between unified cosmic history by -gravity and BIonic system
Alireza Sepehri, Salvatore Capozziello, Mohammad Reza Setare
Recently, the cosmological deceleration-acceleration transition redshift in gravity has been considered in order to address consistently the problem of cosmic evolution. It…
Holographic Cosmology from BIonic Solutions
Alireza Sepehri, Mir Faizal, Mohammad Reza Setare +1
In this paper, we will use a BIonic solution for analyzing the holographic cosmology. A BIonic solution is a configuration of a D3-brane and an anti-D3-brane connected by a wormhol…
Emergence and Expansion of Cosmic Space in BIonic system
A. Sepehri, Farook Rahaman, Anirudh Pradhan +1
Recently, Padmanabhan [arXiv:1206.4916] argued that the expansion rate of the universe can be thought of as the emergence of space as cosmic time progresses and is related to the d…
