相对论自旋算符的两个作用

Two roles of relativistic spin operators

Daniel R. Terno

摘要:

与几个重要量(如角动量)相关的算符扮演着双重角色:它们既是对称群的生成元,又是“可观测量”。对角动量分成“自旋”和“轨道”两部分的不同分裂的分析揭示了这两种作用之间的区别。我们还讨论了自旋观测量的不同选择与违反贝尔不等式的关系。

英文摘要:

Operators that are associated with several important quantities, like angular momentum, play a double role: they are both generators of the symmetry group and ``observables.'' The analysis of different splittings of angular momentum into "spin" and "orbital" parts reveals the difference between these two roles. We also discuss a relation of different choices of spin observables to the violation of Bell inequalities.
