THE TRANSPORT PROPERTIES OF NANOTUBES AND ITS CURVATURE EFFECTS
Preview AbstractThe transport properties across contacts between quantum tubes and metals are studied. The curvature effects on the transmission are also considered. We find that the transmission probability of an electron transporting from the tube into the metal through the contact can be close to 100%. The curvature has a larger effect on the transmission for smaller radii and the effects decrease as the radii increase.
A DYNAMICAL SYSTEM APPROACH TO THE GBIG COSMOLOGY
Preview AbstractWe study the phase space of an extension of the normal DGP cosmology with a cosmological constant on the brane and curvature effect that is incorporated via the Gauss–Bonnet term in the bulk action. We study late-time cosmological dynamics of this scenario within a dynamical system approach. We show that the stable solution of the cosmological dynamics in this model is a de Sitter phase.
