Finite-temperature conductance of interacting quantum wires with Rashba
spin-orbit coupling    [PDF]

Thomas L. Schmidt

We calculate the finite-temperature conductance of weakly interacting one-dimensional quantum wires subject to Rashba spin-orbit coupling and a perpendicular magnetic field. For chemical potentials near the center of the Zeeman gap ($\mu = 0$), two-particle scattering causes deviations from the quantized conductance at finite temperatures. On the other hand, for $|\mu| > 0$, three-particle scattering processes become more relevant. These corrections to the conductance are a consequence of the nonlinear single-particle spectrum, and are thus not accessible within the conventional Luttinger liquid theory.
