The metric of a warped space-time with two extra dimensions is established by means of the Einstein equations in six dimensions and the compactification of two extra dimensions on a square . It is shown that at every among two fixed points our manifold re... see more

In this paper, starting from the common foundation of Connes' noncommutative geometry ( NCG)\cite{Connes1, Connes2, CoLo, Connes3}, various possible alternatives in the formulation of atheory of gravity in noncommutative spacetime are discussed indetails.... see more
A new supersymmetry is proposed for hadrons containing a single heavy quark.This supersymmetry is based on a new approximation to those hadrons, which wewould consider as a further step beyond the spectator light diquark model ofbaryons. The heavy diquark... see more

A theoretical evolutionary model for the nonlinear stability analysis of a planar dust molecular cloud (DMC) in quasi-neutral hydrodynamic equilibrium on the Jeans scales of space and time is developed. It is based on a self-gravitating multi-fluid model ... see more

We report on successful growth of epitaxial and high Curie-temperature Ge1-xMnx quantum dots on Si (001) substrates using the auto-assembled approach. By reducing the growth temperature down to 400 °C, we show that the Mn diffusion into the Si substrate c... see more

In this paper, we present the influence of annealing conditions on structure and magnetic behavior of Ni50_{50}Mn37_{37}Sn13_{13} magnetocaloric alloy prepared by arc-melting technique. The results show that the almost single phase of the full H... see more

The diffusion in one-dimensional disordered lattice with Gaussian distribution of site and transition energies has been studied by mean of kinetic Monte-Carlo simulation. We focus on investigating the influence of energetic disorders and diffusive particl... see more
