[PDF] from manchester.ac.ukLAPIV Grigorieva, KS Novoselov, F Guinea… - 2011 - nature.com In graphene, electron–electron interactions are expected to play a significant role, as the screening length diverges at the charge neutrality point and the conventional Landau theory that enables us to map a strongly interacting electronic liquid into a gas of non-interacting fermions is ...
[PDF] from arxiv.orgAY Nikitin, F Guinea, FJ Garcia-Vidal… - Arxiv preprint arXiv: …, 2011 - arxiv.org Surface plasmon modes supported by graphene ribbon waveguides are studied and classified. The properties of both modes with the field concentration within the ribbon area (waveguiding modes) and on the edges (edge modes) are discussed. The waveguide and edge modes ...
[PDF] from arxiv.org…, AH Neto, F Guinea - Arxiv preprint arXiv:1107.3386, 2011 - arxiv.org Let's consider the scattering problem defined by the Hamiltonian ˆH0 + U, where ˆH0 is nothing but the free Hamiltonian of Eq. (4) in the main text, and U is a generic scattering potential, diagonal in sublattice and spin indices. We take ∆=0 for the moment. We treat the problem in ... Cited by 1
[PDF] from arxiv.orgR de Gail, MO Goerbig, F Guinea… - Arxiv preprint arXiv: …, 2011 - arxiv.org One of the most fascinating aspects of graphene is its band structure which can be fundamentally changed in several different ways by modifying its lattice structure. This happens because the honeycomb lattice of mono- layer graphene has two independent sublattices and the ... Cited by 4 - Related articles - All 2 versions
[PDF] from arxiv.org…, KS Novoselov, AK Geim, F Guinea - Arxiv preprint arXiv: …, 2011 - arxiv.org We report measurements of the cyclotron mass in graphene for carrier concentrations n varying over three orders of magnitude. In contrast to the single-particle picture, the real spectrum of graphene is profoundly nonlinear so that the Fermi velocity describing the spectral slope ...
