    Dynamic impurities in two-dimensional topological-insulator edge states 
    Wozny, Simon; Leijnse, Martin; Erlingsson, Sigurdur I. (2021-11-15)
    Helical edge states of two-dimensional topological insulators show a gap in the density of states (DOS) and suppressed conductance in the presence of ordered magnetic impurities. Here we will consider the dynamical effects on the DOS and transmission ...

    Thermoelectric current in topological insulator nanowires with impurities 
    Erlingsson, Sigurdur I.; Bardarson, Jens H; Manolescu, Andrei (Beilstein Institut, 2018-04-12)
    In this paper we consider charge current generated by maintaining a temperature difference over a nanowire at zero voltage bias. For topological insulator nanowires in a perpendicular magnetic field the current can change sign as the temperature of one ...
