Linear response of doped graphene sheets to vector potentials
A. Principi, Marco Polini, G. Vignale
A two-dimensional gas of massless Dirac fermions (MDFs) is a very useful model to describe low-energy electrons in monolayer graphene. Because the MDF current operator is directly…
Fermi Velocity Enhancement in Monolayer and Bilayer Graphene
Giovanni Borghi, Marco Polini, Reza Asgari +1
In single-layer graphene sheets non-local interband exchange leads to a renormalized Fermi-surface effective mass which vanishes in the low carrier-density limit. We report on a co…
Drude weight, plasmon dispersion, and pseudospin response in doped graphene sheets
Marco Polini, A. H. MacDonald, G. Vignale
Plasmons in ordinary electron liquids are collective excitations whose long-wavelength limit is rigid center-of-mass motion with a dispersion relation that is, as a consequence of…
Collective excitations in one-dimensional ultracold Fermi gases: a comparative study
Wei Li, Gao Xianlong, Corinna Kollath +1
Time-dependent density-functional theory (TDDFT) is a powerful tool to study the non-equilibrium dynamics of inhomogeneous interacting many-body systems. Here we show that the simp…
Time-dependent current-density-functional theory of spin-charge separation and spin drag in one-dimensional ultracold Fermi gases
Gao Xianlong, Marco Polini, Diego Rainis +2
Motivated by the large interest in the non-equilibrium dynamics of low-dimensional quantum many-body systems, we present a fully-microscopic theoretical and numerical study of the…
Density-Functional Theory of Graphene Sheets
Marco Polini, Andrea Tomadin, Reza Asgari +1
We outline a Kohn-Sham-Dirac density-functional-theory (DFT) scheme for graphene sheets that treats slowly-varying inhomogeneous external potentials and electron-electron interacti…
