• Linear response of doped graphene sheets to vector potentials 

    Principi, A.; Polini, Marco; Vignale, Giovanni, 1957- (American Physical Society, 2009)
    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 proportional to the (sublattice) pseudospin ...
