相对论性Stern-Gerlach力
The Relativistic Stern-Gerlach Force
摘要：
电磁场中自旋粒子的相对论拉格朗日量是从粒子静止坐标系中已知的拉格朗日量导出的。由此产生的相对论Stern-Gerlach和托马斯旋进力的粒子，然后来自实验室框架中的拉格朗日。特别是，这个组合Stern-Gerlach-Thomas力的纵向分量不包含与之前的推导[1]中所要求的伽马平方成比例的项。
英文摘要：
The relativistic Lagrangian for a spinning particle in an electromagnetic field is derived from the known Lagrangian in the particle's rest frame. The resulting relativistic Stern-Gerlach and Thomas precession forces on the particle are then derived from the Lagrangian in the laboratory frame. In particular, the longitudinal component of this combined Stern-Gerlach-Thomas force does not contain a term proportional to gamma-squared as was claimed in a previous derivation [1].
