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…
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…
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…
The evolution of Brown-York quasilocal energy due to evolution of Lovelock gravity in a system of M0-branes
Alireza Sepehri, Farook Rahaman, Salvatore Capozziello +2
Recently, it has been suggested in [JHEP 12(2015)003] that the Brown-York mechanism can be used to measure the quasilocal energy in Lovelock gravity. We have used this method in a…
Birth and growth of nonlinear massive gravity and its transition to nonlinear electrodynamics in a system of Mp-branes
Alireza Sepehri, Ahmed Farag Ali
Recently, an interesting mechanism [Phys.Rev.Lett.106:231101,2011] has been proposed which produces all nonlinear terms in massive gravity to all orders . In this work, we reproduc…
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…
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.…
Does HM mechanism work in string theory?
Alireza Sepehri, Somayyeh Shoorvazi, Mohammad Ebrahim Zomorrodian
The correspondence principle offered a unique opportunity to test the Horowitz and Maldacena mechanism at correspondence point "the centre of mass energies around $(M_{s}/(g_{s})^{…
Dirac fields, scalar fields and Final state boundary condition of Black hole
Alireza Sepehri, Mohsen Sarbisheie, Mohammad Amin Harirbafan
We withdraw our paper for one doubt on one of equations .Due to this reason we will check again our calculation and replace the revised version of this paper.
