23. Since the real electron spins do not play a role in the subsequent discussion, we will drop the prefix "pseudo" and refer to pseudospin as "spin."
24. This somewhat strange choice of coordinate system is made to facilitate the comparison with Ref.. Note that from this point on, we are again using the spin orientation chosen in Sec..
