Tachyonic -Tsallis entropy of a thermal tachyonic BIon
Aroonkumar Beesham, Alireza Sepehri
When a brane and an anti-brane come close to each other, the tachyonic potential between them increases and a tachyon wormhole is formed. This configuration, which consists of two…
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…
Tsallis -entropy in an accelerating BIon
Hossein Ghaforyan, Somayeh Shoorvazi, Alireza Sepehri +1
In this research, we consider thermodynamically the behaviour of an accelerating BIon and show that the entropy of this system has the form of Tsallis entropy. A BIon is a system t…
MOG without anomaly
Alireza Sepehri, Tooraj Ghaffary, Yaghoob Naimi
We obtain the action of Moffat's Modified Gravity, (MOG), a scalar-tensor-vector theory of gravitation, by generalizing the Horava-Witten mechanism to fourteen dimensions. We show…
The BIonic diode in a system of trigonal manifolds
Alireza Sepehri, Mohd. Zeyauddin, Anirudh Pradhan
A BIonic diode is constructed of two polygonal manifolds connected by a Chern-Simons manifold. The shape and the angle between atoms of molecules on the boundary of two polygonal m…
Quarkonium in a thermal BIon
Alireza Sepehri, Richard Pincak, Michal Hnatič +2
In the present article, the authors intend to propose a new theory which potentially allows the propagation of the formation and the evolution of quarkonium in a thermal BIon. When…
A mathematical model for DNA
Alireza Sepehri
Recently, some authors have shown that a DNA molecule produces electromagnetic signals and communicates with other DNA molecules or other molecules. In fact, a DNA acts like a rece…
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…
Birth of the GUP and its effect on the entropy of the Universe in Lie--algebra
Alireza Sepehri, Anirudh Pradhan, Richard Pincak +3
In this paper, the origin of the generalized uncertainty principle (GUP) in an -dimensional theory with Lie--algebra is considered. This theory which we name GLNA(Generalized…
The origin of Chern-Simons modified gravity from an 11 + 3-dimensional manifold
J. A. Helayël-Neto, Alireza Sepehri
In this contribution, it is our aim to show that the Chern-Simons terms of modified gravity can be understood as generated by the addition of a 3-dimensional algebraic manifold to…
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…
Recovery of hadronic cross section inside the mini black holes at LHC
Tooraj Ghaffary, Alireza Sepehri, Sayeedul Islam +1
In curved space time inside the shell of TeV black holes, many gluons and quarks produce due to Unruh effect, interact with each other and create Higgs boson. Studying the Unruh ef…

Alireza Sepehri, Richard Pincak
Recently, Padmanabhan has discussed that the expansion of the cosmic space is due to the difference between the number of degrees of freedom on the boundary surface and the number…
Emergence of the world with Lie-N-algebra and M-dimensions from nothing
Alireza Sepehri, Richard Pincak
In this paper, we propose a new model in Lie-N-algebra that removes big bang singularity and produces the world with all it's objects and dimensions from nothing. We name this theo…
