Engineering artificial graphene in a two-dimensional electron gas
M. Gibertini, A. Singha, V. Pellegrini +5
At low energy, electrons in doped graphene sheets behave like massless Dirac fermions with a Fermi velocity which does not depend on carrier density. Here we show that modulating a…
Andreev reflection in graphene nanoribbons
Diego Rainis, Fabio Taddei, Fabrizio Dolcini +2
We study Andreev reflection in graphene nanoribbon/superconductor hybrid junctions. By using a tight-binding approach and the scattering formalism we show that finite-size effects…
The Role of Electron-electron Interactions in Graphene ARPES Spectra
Marco Polini, Reza Asgari, Giovanni Borghi +3
We report on a theoretical study of the influence of electron-electron interactions on ARPES spectra in graphene that is based on the random-phase-approximation and on graphene's m…
Theory of the Pseudospin Resonance in Semiconductor Bilayers
Saeed H. Abedinpour, Marco Polini, A. H. MacDonald +3
The pseudospin degree of freedom in a semiconductor bilayer gives rise to a collective mode analogous to the ferromagnetic resonance mode of a ferromagnet. We present a theory of t…
Graphene: A Pseudochiral Fermi Liquid
Marco Polini, Reza Asgari, Yafis Barlas +2
Doped graphene sheets are pseudochiral two-dimensional Fermi liquids with abnormal electron-electron interaction physics. We address graphene's Fermi liquid properties quantitative…
Ground-state densities and pair correlation functions in parabolic quantum dots
M. Gattobigio, P. Capuzzi, M. Polini +2
We present an extensive comparative study of ground-state densities and pair distribution functions for electrons confined in two-dimensional parabolic quantum dots over a broad ra…
