black hole at N=2 supergravity
B. Pourhassan, J. Sadeghi, A. Chatrabhuti
In this paper, we consider the charged non-extremal black hole at five dimensional N = 2 supergravity. We study thermodynamics of AdS_{5} black hole with three equal charges (q_{1}…
Baryon Binding Energy in Sakai-Sugimoto Model
J. Sadeghi, M. R. Pahlavani, S. Heshmatian +1
The binding energy of baryon has been studied in the dual string theory with a black hole interior. In this picture baryon is constructed of a brane vertex…
Vacuum quantum effect for curved boundaries in static Robertson--Walker spacetime
M R Setare, J Sadeghi
The energy-momentum tensor for a massless conformally coupled scalar field in the region between two curved boundaries in static Robertson--Walker spacetime is investigated.…
Thermodynamical Stability of Hagedorn and Radiation Regimes in Closed String Gas Cosmology
J. Sadeghi, H. Farahani, B. Pourhassan
In this paper, we investigate thermal equilibrium in string gas cosmology which is dominated by closed string.We consider two interesting regimes, Hagedorn and radiation regimes.We…
Non-minimal Maxwell-Modified Gauss-Bonnet Cosmologies: Inflation and Dark Energy
J Sadeghi, M R Setare, A Banijamali
In this paper we show that power-law inflation can be realized in non-minimal gravitational coupling of electromagnetic field with a general function of Gauss-Bonnet invariant. Suc…
Cosmic acceleration and crossing of in non-minimal modified Gauss-Bonnet gravity
J Sadeghi, M R Setare, A Banijamali
Modified Gauss-Bonnet, i.e, gravity is a possible explanation of dark energy. Late time cosmology for the gravity non-minimally coupled with a free massless scalar fi…
