A set of “spherical vector” operators ?? (? = ±1,0) is defined by its commutation relations with a set of angular momentum operators:
[?? , ??] = ℏ???
[?±,??] = ℏ√((1 − ?)(2 ± ?)) ??±1
Could ?± and ?? be considered a set of spherical vector operators themselves, when scaled by some appropriate constants? If no, demonstrate which commutation relation they fail to satisfy. If yes, write ?1,?0, ?−1 in terms of the angular momentum operators, and show that they satisfy all relevant relations.
