For static crystals it is well known that electronic states are doubly degenerate in their spin degree of freedom in the presence of time reversal and inversion symmetries. This degeneracy can only be lifted by either (i) breaking time…

Persistent spin textures are highly desirable for applications in spintronics as they may allow for long carrier spin lifetimes. However, they are also rare as only four point groups can host such textures, and even for these four groups,…
