Expansion and contraction of accretion disks of a rotating thermal BIon in a Rindler space-time
Aroonkumar Beesham, Alireza Sepehri
In this paper, we consider the evolution of accretion disks of a rotating BIon in a Rindler space-time. This space-time emerges because of the acceleration of the disks in a BIon.…
Emergence and expansion of cosmic space in an accelerating BIon
Aroonkumar Beesham, Alireza Sepehri
We generalize the Padmanabhan [arXiv:hep-th/1206.4916] mechanism to an accelerating BIon and show that the difference between the number of degrees of freedom on the boundary surfa…
On the origin of generalized uncertainty principle from compactified M5-brane
Alireza Sepehri, Anirudh Pradhan, A. Beesham
In this paper, we demonstrate that compactification in M-theory can lead to a deformation of field theory consistent with the generalized uncertainty principle (GUP).We observe tha…
Role of higher -dimensional evolving wormholes in the formation of a big rip singularity
Mohammad Reza Setare, Alireza Sepehri
We study the evolutions of 4D universe on the M2-M5 BIon in the thermal background. The BIon consists of a D-brane and a parallel anti-D-brane which a wormhole connects them. When…
Cosmological expansion and contraction from Pauli exclusion principle in -branes
Alireza Sepehri, Ahmed Farag Ali, Kazuharu Bamba +5
We show that the Pauli exclusion principle in a system of -branes can give rise to the expansion and contraction of the universe which is located on an -brane. We start wit…
Current density and conductivity through modified gravity in the graphene with defects
Alireza Sepehri, Richard Pincak, Kazuharu Bamba +2
We propose a model describing the evolution of the free electron current density in graphene. Based on the concept of Mp-branes, we perform the analysis using the difference betwee…
Teleparallel loop quantum cosmology in a system of intersecting branes
Alireza Sepehri, Anirudh Pradhan, A. Beesham +1
Recently, some authors have removed the big bang singularity in teleparallel Loop Quantum Cosmology (LQC) and have shown that the universe may undergo a number of oscillations. We…
Emergence and oscillation of cosmic space by joining M1-branes
Alireza Sepehri, Farook Rahaman, Salvatore Capozziello +2
Recently, it has been proposed by Padmanabhan that the difference between the number of degrees of freedom on the boundary surface and the number of degrees of freedom in a bulk re…
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…
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…
Stability of cylindrical thin shell wormhole during evolution of universe from inflation to late time acceleration
M. R. Setare, A. Sepehri
In this paper, we consider the stability of cylindrical wormholes during evolution of universe from inflation to late time acceleration epochs. We show that there are two types of…
Constructing warm inflationary model in brane-antibrane system
M. R. Setare, A. Sepehri, V. Kamali
Recently, various observational data predict a possibility that inflation may naturally occur in a warm region. In this scenario, radiation is produced during the inflation epoch a…
