论文摘要
旋转轨耦合的Rashba和Dresselhaus类型是两种典型的线性耦合形式。我们建立了一个模型的基本物理，可以将其视为Rashba和Dresselhaus旋转轨道耦合的双重版本。该模型描述了旋转轨道系统中一类无质量的狄拉克费物的低能物理。无质量的狄拉克费米的物理特性取决于自旋轨道系数的数学关系。对于相同的Rashba和Dresselhauss耦合常数，在此模型中出现了与无质量的双发性毛茸茸的螺旋螺旋相结合的持续旋转螺旋。该模型描述的自旋轨道耦合系统具有从旋转技术到量子计算的潜在技术应用。
The Rashba and Dresselhaus types of spin-orbit coupling are two typical linear coupling forms. We establish the fundamental physics of a model which can be viewed as the double version of the Rashba and Dresselhaus spin-orbit coupling. This model describes the low energy physics of a class of massless Dirac fermions in spin-orbit systems. The physical properties of the massless Dirac fermions are determined by the mathematical relations of spin-orbit coefficients. For equal Rashba and Dresselhauss coupling constants, k-independent eigenspinors and a persistent spin helix combined with massless birefringent Dirac fermions emerge in this model. The spin-orbit coupled systems described by this model have potential technological applications from spintronics to quantum computation.
