Momentum-dependent spin selection rule in photoemission with glide symmetry
Momentum-dependent spin selection rule in photoemission with glide symmetry
We present a comprehensive theory of the spin- and angle-resolved photoemission spectroscopy (SARPES) of materials with glide-mirror symmetry, focusing on the role of glide symmetry in the spin selection rule. In the glide-symmetric SARPES configuration, where the surface of a material, the incoming light, and the outgoing photoelectrons are invariant …
