Electromagnetic waves in NUT space: Solutions to the Maxwell equations
Mohammad Nouri-Zonoz
In this paper, using the Newman-Penrose formalism, we find the Maxwell equations in NUT space and after separation into angular and radial components solve them analytically. All t…
Non-locality and Medium Effects in the Exclusive Photoproduction of Eta Mesons on Nuclei
M. Hedayati-Poor, S. Bayegan, H. S. Sherif
A relativistic model for the quasifree exclusive photoproduction of mesons on nuclei is extended to include both non-local and medium effects. The reaction is assumed to procee…
Spin 0 and spin 1/2 particles in a constant scalar-curvature background
M. Alimohammadi, B. Vakili
We study the Klein-Gordon and Dirac equations in the presence of a background metric ds^2 = -dt^2 + dx^2 + e^{-2gx}(dy^2 + dz^2) in a semi-infinite lab (x>0). This metric has a con…
Bohmian Quantum Gravity in the Linear Field Approximation
Ali Shojai, Fatimah Shojai
In this paper we have applied Bohmian quantum theory to the linear field approximation of gravity and present a self--consistent quantum gravity theory in the linear field approxim…
Large-N limit of the non-local 2D Yang-Mills and generalized Yang-Mills theories on a cylinder
Khaled Saaidi, Mohammad Khorrami
The large-group behavior of the nonlocal YM's and gYM's on a cylinder or a disk is investigated. It is shown that this behavior is similar to that of the corresponding loca…
Investigation of a Protein Complex Network
A. R. Mashaghi, A. Ramezanpour, V. Karimipour
The budding yeast {\it Saccharomyces cerevisiae} is the first eukaryote whose genome has been completely sequenced. It is also the first eukaryotic cell whose proteome (the set of…
