Electrically controllable magnetism in twisted bilayer graphene
Luis A. Gonzalez-Arraga, J. L. Lado, Francisco Guinea +1
Twisted graphene bilayers develop highly localised states around AA-stacked regions for small twist angles. We show that interaction effects may induce either an antiferromagnetic…
Continuum model for chiral induced spin selectivity in helical molecules
Ernesto Medina, Luis A. González-Arraga, Daniel Finkelstein-Shapiro +2
A minimal model is exactly solved for electron spin transport on a helix. Electron transport is assumed to be supported by well oriented type orbitals on base molecules formi…
Tunneling and transmission resonances of a Dirac particle by a double barrier
Victor M. Villalba, Luis Gonzalez-Arraga
We calculate the tunneling process of a Dirac particle across two square barriers separated a distance , as well as the scattering by a double cusp barrier where the centers of…
