Two-body problem in graphene
J. Sabio, F. Sols, F. Guinea
We study the problem of two Dirac particles interacting through non-relativistic potentials and confined to a two-dimensional sheet, which is the relevant case for graphene layers.…
Generating quantizing pseudomagnetic fields by bending graphene ribbons
F. Guinea, A. K. Geim, M. I. Katsnelson +1
We analyze the mechanical deformations that are required to create uniform pseudomagnetic fields in graphene. It is shown that, if a ribbon is bent in-plane into a circular arc, th…
Entanglement of spin chains with general boundaries and of dissipative systems
T. Stauber, F. Guinea
We analyze the entanglement properties of spins (qubits) close to the boundary of spin chains in the vicinity of a quantum critical point and show that the concurrence at the bound…
Synthetic electric fields and phonon damping in carbon nanotubes and graphene
F. von Oppen, F. Guinea, E. Mariani
Smoothly varying lattice strain in graphene affects the Dirac carriers through a synthetic gauge field. When the lattice strain is time dependent, as in connection with phononic ex…
Impurity induced spin-orbit coupling in graphene
A. H. Castro Neto, F. Guinea
We study the effect of impurities in inducing spin-orbit coupling in graphene. We show that the sp3 distortion induced by an impurity can lead to a large increase in the spin-orbit…
