 Title : Finite-temperature conductance of interacting quantum wires with Rashba spin-orbit coupling Language : English Author, co-author : Schmidt, Thomas [University of Basel > Department of Physics] Publication date : 2013 Journal title : Phys. Rev. B Volume : 88 Pages : 235429 Peer reviewed : Yes Abstract : [en] We calculate the finite-temperature conductance of clean, weakly interacting one-dimensional quantum wires subject to Rashba spin-orbit coupling and a magnetic field. For chemical potentials near the center of the Zeeman gap ($\mu=0$), two-particle scattering causes the leading deviation from the quantized conductance at finite temperatures. On the other hand, for $|\mu| > 0$, three-particle scattering processes become more relevant. These deviations are a consequence of the strongly nonlinear single-particle spectrum, and are thus not accessible using Luttinger liquid theory. We discuss the observability of these predictions in current experiments on InSb nanowires and in spiral liquids,'' where a spontaneous ordering of the nuclear spins at low temperatures produces an effective Rashba coupling.
