在存在电磁场的情况下，加速系统中与自旋相关的惯性力是从一般协变狄拉克方程导出的。自旋流是通过弹道和扩散状态下自旋轨道耦合最低阶的力来评估的。我们将线性加速度对电子的惯性效应解释为有效电场，并表明高频谐振器中的机械振动可以通过线性加速度增强的自旋轨道相互作用产生自旋电流。
The spin-dependent inertial force in an accelerating system under the presence of electromagnetic fields is derived from the generally covariant Dirac equation. Spin currents are evaluated by the force up to the lowest order of the spin-orbit coupling in both ballistic and diffusive regimes. We give an interpretation of the inertial effect of linear acceleration on an electron as an effective electric field and show that mechanical vibration in a high frequency resonator can create a spin current via the spin-orbit interaction augmented by the linear acceleration.
