Improving student understanding of electrodynamics: the case for differential forms
Sébastien Fumeron, Bertrand Berche, Fernando Moraes
The illuminating role of differential forms in electromagnetism is seldom discussed in the classroom. It is the aim of this article to bring forth some of the relevant insights tha…
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…
