Abstract: Scattering between electrons in the material graphene can cause these particles to flow like a viscous liquid. Such flow, which has previously been detected using measurements of electrical resistance, has now been visualized. Viscous flow… read more here.

Abstract: We theoretically study a current switch that exploits the phase acquired by a charge carrier as it tunnels through a potential barrier in graphene. The system acts as an interferometer based on an armchair graphene… read more here.

Abstract: We have developed a Hartree-Fock theory for electrons on a honeycomb lattice aiming to solve a long-standing problem of the Fermi velocity renormalization in graphene. Our model employs no fitting parameters (like an unknown band… read more here.
