Dirac cones reshaped by interaction effects in suspended graphene

[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 ...

Edge and waveguide THz surface plasmon modes in graphene micro-ribbons

[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 ...

Elliot-Yafet mechanism in graphene

[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 ...

Topologically Protected Zero Modes in Twisted Bilayer Graphene

[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 ...

Dirac cones reshaped by interaction effects in suspended graphene

[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 ...
