    Spin-filtering and charge- and spin-switching effects in a quantum wire with periodically attached stubs

    Spin-dependent electron transport in a periodically stubbed quantum wire in the presence of Rashba spin-orbit interaction (SOI) is studied via the nonequilibrium Green’s function (GF) method combined with the ...

    Spin-dependent electron transport in a Rashba quantum wire with rough edges

    We investigate theoretically the spin-dependent electron transport in a Rashba quantum wire with rough edges. The charge and spin conductances are calculated as function of the electron energy and wire length ...

    Electronic transport for impurity-doped armchair-edge graphene nanoribbons

    We investigate the electronic transport for an impurity-doped armchair-edge graphene nanoribbon (AGNR), with 7 or 8 dimer lines along zigzag direction, sandwiched between two normal leads. By using the standa...

    Electronic structures for armchair-edge graphene nanoribbons under a small uniaxial strain

    We theoretically investigate the electronic structures for armchair-edge graphene nanoribbons (AGNRs) under a small in-plane uniaxial strain along armchair (longitudinal) and zigzag (transversal) direction, r...

    Temperature-dependent transport and spin accumulation in a quantum wire with Rashba spin-orbit interaction

    We study the theory of temperature-dependent electron transport, spin polarization, and spin accumulation in a Rashba spin-orbit interaction (RSOI) quantum wire connected nonadiabatically to two normal conduct...

    Moving nonlinear localized vibrational modes for a one-dimensional homogenous lattice with quartic anharmonicity

    Moving nonlinear localized vibrational modes (i.e. discrete breathers) for the one-dimensional homogenous lattice with quartic anharmonicity are obtained analytically by means of a semidiscrete approximation plus...
