赝自旋1/2自由度的时间反演

Time reversal of pseudo-spin 1/2 degrees of freedom

R. Winkler, U. Zülicke

摘要:

我们表明,根据时间反转下的行为,伪自旋1/2自由度可以分为两种类型。一类自旋在时间反演下具有三个笛卡尔分量均为奇数的普通自旋性质。对于第二种类型,只有一个组件是奇数,而其他两个是偶数。我们讨论了这第二种类型的伪自旋的几个物理例子,并突出可观察到的结果,可以用来区分它从普通的自旋。

英文摘要:

We show that pseudo-spin 1/2 degrees of freedom can be categorized in two types according to their behavior under time reversal. One type exhibits the properties of ordinary spin whose three Cartesian components are all odd under time reversal. For the second type, only one of the components is odd while the other two are even. We discuss several physical examples for this second type of pseudo-spin and highlight observable consequences that can be used to distinguish it from ordinary spin.
