论文摘要
螺旋状态的表征可以通过检查重点行为的存在来执行，该行为的存在是在纳米线（NWS）中探测的电导中的浸入，并具有强旋转轨道耦合（SOC）（SOC）和垂直磁场下。另一方面，参考文献中描述的实验。 1观察到在没有磁场的情况下的重点行为，这是通过旋转两粒子反向散射来解释的。从理论上讲，我们表明，对重点行为的观察是由于多通道散射机制引起的，当存在有效的有吸引力的电位和不同通道之间的耦合时，这会导致传播的降低。这两种成分均由SOC在NWS的运输特性中提供。
The characterization of helical states can be performed by checking the existence of the re-entrant behaviour, which appears as a dip in the conductance probed in nanowires (NWs) with strong spin-orbit coupling (SOC) and under perpendicular magnetic field. On the other hand, the experiment described in Ref. 1 observed the re-entrant behaviour in the absence of a magnetic field, which was explained through spin-flipping two-particle backscattering. We theoretically show that the observation of the re-entrant behaviour is due to a multi-channel scattering mechanism, which causes a reduction of the transmission when an effective attractive potential and coupling between different channels are present. Both ingredients are provided by the SOC in the transport properties of NWs.
