Magnetic and geometric effects on the electronic transport of metallic nanotubes
Felipe Serafim, Fernando A. N. Santos, Jonas R. F. Lima +3
The investigation of curved low-dimensional systems is a topic of great research interest. Such investigations include two-dimensional systems with cylindrical symmetry. In this wo…
Spin current generation and control in carbon nanotubes by combining rotation and magnetic field
Márcio M. Cunha, Jonas R. F. Lima, Fernando Moraes +2
We study the quantum dynamics of ballistic electrons in rotating carbon nanotubes in the presence of a uniform magnetic field. When the field is parallel to the nanotube axis, the…
On the energy of topological defect lattices
B. Berche, S. Fumeron, F. Moraes
Since the logarithm function is the solution of Poisson's equation in two dimensions, it appears as the Coulomb interaction in two dimensions, the interaction between Abrikosov flu…
Geometrical optics limit of phonon transport in a channel of disclinations
Sébastien Fumeron, Bertrand Berche, Fernando Moraes +2
The presence of topological defects in a material can modify its electrical, acoustic or thermal properties. However, when a group of defects is present, the calculations can becom…
Using torsion to manipulate spin currents
Sébastien Fumeron, Bertrand Berche, Ernesto Medina +2
We address the problem of quantum particles moving on a manifold characterised by the presence of torsion along a preferential axis. In fact, such a torsion may be taylored by the…
Geometric effects in the electronic transport of deformed nanotubes
Fernando Santos, Sébastien Fumeron, Bertrand Berche +1
Quasi-two-dimensional systems may exibit curvature, which adds three-dimensional influence to their internal properties. As shown by da Costa \cite{dacosta}, charged particles movi…
