Transition to complete synchronization in phase coupled oscillators with nearest neighbours coupling
Hassan F. El-Nashar, Paulsamy Muruganandam, Fernando F. Ferreira +1
We investigate synchronization in a Kuramoto-like model with nearest neighbour coupling. Upon analyzing the behaviour of individual oscillators at the onset of complete synchroniza…
Effect of Spin-Torsion Interaction on Raychaudhuri Equation
M. I. Wanas, M. A. Bakry
Raychaudhuri equation is generalized in the parameterized absolute parallelism geometry. This version of absolute parallelism is more general than the conventional one. The general…
Simple two Higgs doublet model
Renata Jora, Sherif Moussa, Salah Nasri +2
We study a simple two Higgs doublet model which reflects, in a phenomenological way, the idea of compositeness for the Higgs sector. It is relatively predictive. In one scenario, i…
Charged Dilaton, Energy, Momentum and Angular-Momentum in Teleparallel Theory Equivalent to General Relativity
Gamal Gergess Lamee Nashed
We apply the energy-momentum tensor to calculate energy, momentum and angular-momentum of two different tetrad fields. This tensor is coordinate independent of the gravitational fi…
Møller's energy of the Kerr-NUT Metric
Gamal G. L. Nashed
The energy distribution of the Kerr-NUT space-time is calculated using Møller's energy-momentum complex within the framework of the Riemannian geometry.
Sterile neutrino dark matter in extension of the standard model and galactic 511 keV line
Shaaban Khalil, Osamu Seto
Sterile right-handed neutrinos can be naturally embedded in a low scale gauged extension of the standard model. We show that, within a low reheating scenario, such a n…
